Abstract
BACKGROUND The prognostic significance of Q waves and T-wave inversions (TWI) combined and separately in STEMI patients undergoing primary PCI has not been well established in previous studies. METHODS We included 7,831 patients from the TOTAL trial and divided the patients into categories based on Q waves and TWIs in the presenting ECG. The primary outcome was a composite of cardiovascular death, recurrent myocardial infarction (MI), cardiogenic shock or new or worsening NYHA class IV heart failure within one year. The study evaluated the effect of Q waves and TWI on the risk of primary outcome and all-cause death, and whether patient benefit of aspiration thrombectomy differed between the ECG categories. RESULTS Patients with Q+TWI+ (Q wave and TWI) pattern had higher risk of primary outcome compared to patients with Q-TWI- pattern [33 (10.5%) vs. 221 (4.2%); adjusted hazard ratio (aHR) 2.10; 95% CI, 1.45-3.04; p<0.001] within 40-days' period. When analyzed separately, patients with Q waves had a higher risk for the primary outcome compared to patients with no Q waves in the first 40 days [aHR 1.80; 95% CI, 1.48-2.19; p<0.001] but there was no additive risk after 40 days. Patients with TWI had a higher risk for primary outcome only after 40 days when compared to patients with no TWI [aHR 1.63; 95% CI, 1.04-2.55; p=0.033]. There was a trend towards a benefit of thrombectomy in patients with the Q+TWI+ pattern. CONCLUSIONS Q waves and TWI combined (Q+TWI+ pattern) in the presenting ECG is associated with unfavourable outcome within 40-days. Q waves tend to affect short-term outcome, while TWI has more effect on long-term outcome.

Abstract
Background Spinal cord injury (SCI) is a significant cause of morbidity and mortality with an incidence of 40-83/million/year. Sympathetic denervation in SCI leads to cardiovascular abnormalities including orthostatic hypotension, rhythm disturbance, and repolarization changes. Electrocardiographic (ECG) findings include bradyarrhythmias, ectopic beats, long QT interval, and ST-T changes that may be mistaken for myocardial ischaemia. Case summary A patient in their 40 s with free past medical history was referred to our centre with the diagnosis of non-ST elevation acute coronary syndrome. On presentation, chest pain was diffuse and radiating to the back. Twelve-lead ECG showed deep symmetrical T-wave inversion. Echocardiography and cardiac troponin were normal. The patient was scheduled for multi-slice computed tomography coronary angiography which was normal; however, a few hours after admission, the patient developed rapidly progressive motor weakness in both lower limbs with urine retention. Examination revealed motor power Grade 1 in both lower limbs. All sensations were diminished with a sensory level at T6. Urgent magnetic resonance imaging spine revealed neoplastic infiltration of the whole vertebrae with D5/D6 fracture exerting spinal cord compression. The patient was referred for urgent decompression surgery. Conclusion Electrocardiographic changes could be the earliest sign for ongoing SCI. ST-elevation is reported in higher levels of complete injury, while ST depression and inverted T waves can occur independent of lesion level or severity. Misinterpretation of these changes may cause a delay in reaching the correct diagnosis. We highlight the importance of considering neurological causes for ischaemic-like ECG changes, as early recognition could prevent irreversible functional loss.

Abstract
Hypertrophic cardiomyopathy is one of the main causes of sudden cardiac death in young athletes. Differentiating between this pathological condition and 'athlete's heart' can be quite challenging, warranting a thorough clinical and imaging assessment. Clinicians often rely on detraining-induced attenuation of electrocardiographic and echocardiographic findings as a means of distinguishing between pathological and physiological cardiac remodeling. This report describes detraining-related regression of left ventricular hypertrophy in a young soccer player with a diagnosis of hypertrophic cardiomyopathy. It challenges the dogma that regression of electrocardiographic abnormalities and left ventricular hypertrophy is exclusive to physiological remodeling and questions the impact of exercise training in the phenotypic expression and progression of hypertrophic cardiomyopathy.

Abstract
One of the rare causes of diffuse T-wave inversion (TWI) in electrocardiogram (ECG) is memory T-waves. This should be considered among the differentials of diffuse TWI in ECG of patients presenting to the emergency department (ED), especially when they have previous episodes of ventricular tachycardia (VT) or pacemaker implantation or Wolff-Parkinson-White syndrome. These TWIs are benign and do not require any treatment. However, it is of paramount importance for the emergency physician to differentiate it from ischemia-related T-wave changes. In the following case series, we report three cases of memory T-waves. Two of the cases had TWI in leads II, III, aVF, and V3 to V6 following reversion of VT. The other patient, with a VVI (Left ventricle paced, Left ventricle sensed, Inhibition to sensing) pacemaker, had memory T-waves in the ECG taken during normal sinus rhythm. In all the three patients, we considered memory T-waves to be the possible cause of TWI. The electrocardiographic diagnostic criteria for memory T-waves are positive T in lead aVL and positive/isoelectric T in the lead I; and precordial TWI >inferior TWI. These criteria are 92% sensitive and 100% specific. In the following case series, we also provide an algorithmic approach for patients with suspected memory T-waves in their 12-lead ECG when they present to the ED.

Abstract
BACKGROUND Although T-wave inversions are nonspecific, in the appropriate clinical setting, the pattern of negative biphasic T-waves or T-wave inversion in V2-V3 can indicate critical stenosis of the left anterior descending coronary artery (i.e. "anterior Wellens sign"). Recently tall T-waves in V2-V3 have been reported in association with posterior reperfusion (i.e."posterior Wellens sign"). Less commonly, negative biphasic T-waves or T-wave inversions in the inferior leads have been reported in association with critical stenosis of the right coronary artery (RCA) or left circumflex artery (LCx). We present a case where T wave inversions (i.e. "inferior Wellens sign") and a tall T-wave in V2-V3 (i.e. "posterior Wellens sign") preceded the development of an inferior-posterior ST-elevation myocardial infarction (STEMI). CASE REPORT A 37-year-old man presented to the Emergency Department for one day of chest pain. On arrival, his pain had resolved, and his 1st ECG showed inverted/biphasic T-waves in lead III and aVF and a tall T wave in V2-V3. Three- and one-half hours after arrival, his chest pain returned and his ECG showed an inferior-posterior STEMI. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: New, focal T-wave inversions in an anatomic distribution may be an early warning sign of impending myocardial infarction. Careful attention to the T-waves during asymptomatic periods may assist in identifying patients that may have critical stenosis of an underlying coronary artery. In this case, T-wave inversions in the inferior leads, along with a tall T-wave in V2-V3, were seen prior to the development of an inferior-posterior STEMI.

Abstract
Particularities of African descent patient's electrocardiogram have been described for many years. Variations such as higher QRS voltage, early repolarization pattern, precordial T-wave inversion and anterior ST segment elevation associated with T-wave inversion are more frequently observed. Ignorance of these variations can lead to misdiagnosis or therapeutic negligence. We present the electrocardiographic particularities attributed to the patient of African origin.

Abstract
Purpose Cardiac involvement with COVID-19 infection has become evident by elevated troponin, cardiac arrhythmias, ST segment elevation, myocarditis, fulminant heart failure, and sudden cardiac death. We aimed to describe the association of COVID-19 and T-wave inversion (TWI) in a large case series. Methods We conducted an observational, retrospective study of confirmed COVID-19 cases with at least one electrocardiogram (ECG) in a large hospital in New York City (March 23, 2020–April 23, 2020). Patients with new TWI or pseudonormalization were further analyzed. Mortality and the need for invasive mechanical ventilation were the main outcomes. Results A total of 3225 patients were screened; 195 (6%) were selected for further analysis: 181 with TWI and 14 with T-wave pseudonormalization. Mean age was 66 ± 7 years; 51% were male. TWI were more commonly noted in the lateral (71%), followed by anterior (64%), inferior (57%), and septal (26%) leads. A total of 44 patients (23%) had elevated troponin. A total of 50 patients died (26%). Mortality rates of 35%, and 52% were observed in patients with diffuse TWI, and elevated troponin, respectively. Mortality rate of 80% was observed in patients with both elevated troponin and diffuse TWI. Additionally, 30% of the entire cohort and 58% of patients with elevated troponin required invasive mechanical ventilation. Conclusion Our study demonstrates that new TWI is a relatively common finding in COVID-19 patients. Importantly, our findings suggest that new TWI or T-wave pseudonormalization, particularly with elevated troponin, was associated with higher rates of mechanical ventilation and in-hospital mortality.

Abstract
Background Severe electrocardiographic (ECG) abnormalities in asymptomatic subjects correlate with cardiovascular risk. Hypothesis The role of minor ECG abnormalities is less well‐known. We evaluated the association between a negative T‐wave and mortality, as a possible marker for prognosis. Methods A prospective, population‐based cohort, examined at 50 years, and followed until death. Time to death (event rates) and predictive role of a negative T‐wave (Cox regression) were analyzed. Results Participants (n = 839) with a negative T‐wave (7.3%) had significantly higher blood pressure (BP) (mean systolic 157.9 mmHg vs 136.8 mmHg without negative T‐wave, P = <.0001). A negative T‐wave correlated with elevated risk (hazard ratio [HR] [95% CI] [confidence interval]) for all‐cause and cardiovascular (CV) death (1.59 (1.20‐2.11) P = .0012 vs 1.91 (1.34‐2.73) P = .0004). The association remained after excluding coexisting Q/QS patterns and ST‐junction/segment depression ECG abnormalities (1.66 [1.13‐2.44] P = .0098 for all‐cause vs 1.87 [1.13‐3.09] P = .015 for CV death). Death from other causes was not associated with a negative T‐wave. A major negative T‐wave carried higher risk than a minor (2.17 [1.25‐3.76] P = .0062 vs 1.78 [1.13‐2.79] P = .012) for CV death. Conclusion A negative T‐wave at 50 years, in asymptomatic individuals, carried an increased risk of all‐cause and CV death during lifetime follow‐up.

Abstract
BACKGROUND Precordial T-wave inversion (TWI) is an important diagnostic criterion for arrhythmogenic right ventricular cardiomyopathy (ARVC). OBJECTIVE This study aimed to characterize the initial repolarization features of definite ARVC in patients who first presented with right ventricular outflow tract ventricular arrhythmia (RVOT-VA) and TWI. METHODS Patients who presented with RVOT-VA and TWI ≥ V2 were retrospectively assessed. The initial characteristics of repolarization between patients with and without a final diagnosis of definite ARVC during follow-up were compared. RESULTS TWI ≥ V2 was observed in 61 of 553 patients (mean age: 44.1 ± 14.7 years; 14 men) with RVOT-VAs. After an average follow-up time of 54.9 ± 33.7 months, 31 (50.8%) patients were classified into the definite ARVC group and 30 (49.2%) into the non-definite ARVC group. The disappearance of precordial TWI ≥ V2 was observed in eight (13.1%) patients after the elimination of RVOT-VAs. In a multivariate analysis of the initial electrocardiogram features, only fragmented QRS [odds ratio (OR): 15.45, 95% confidence interval (CI): 1.61-148.26, p = 0.02] and precordial V2 TpTe interval (OR: 1.03, 95% CI: 1.01-1.06, p = 0.02) could independently predict definite ARVC during longitudinal follow-up. An initial V2 TpTe cutoff value > 88.5 ms could predict the final diagnosis of definite ARVC, with a sensitivity and specificity of 74.2% and 78.6%, respectively. CONCLUSIONS Despite the high risk of ARVC in RVOT-VAs and TWI ≥ V2, "normalization" of TWI was observed after ventricular arrhythmia elimination in 13.1% of the patients. Fragmented QRS and longer V2 TpTe interval were associated with definite ARVC during longitudinal follow-up.

Abstract
BACKGROUND T-wave inversion (TWI) is not considered useful for diagnosing pediatric arrhythmogenic right ventricular cardiomyopathy (ARVC), because right precordial TWI in ARVC resembles a normal juvenile pattern. OBJECTIVES The aims of this study were to clarify the electrocardiographic (ECG) characteristics of pediatric ARVC to distinguish those patients from healthy children. METHODS Between 1979 and 2017, 11 ARVC patients under 18 years old were registered and compared with school screening ECGs from 48,401 healthy children. RESULTS The mean age at the first arrhythmic event or diagnosis was 13.3 ± 4.7 years. Nine patients were asymptomatic initially and were found by ECG screening, but 6 developed severe symptoms during the follow-up. Healthy children had a normal juvenile pattern, while ARVC children, especially symptomatic patients, had a significant tendency to have inferior and anterior TWI. The phenomenon of T-wave discontinuity (TWD) in which the TWI became deeper from V1 to V3 and suddenly turned positive in V5 was significantly more frequent in ARVC (60%) than healthy children (0.55%). Anterior TWI and TWD were also significantly more frequent in those who developed severe symptoms. The sensitivity and specificity of TWD were 60% (95% CI, 31-83%), and 99% (95% CI, 99-99%) to distinguish ARVC from healthy children, as well as 100% (95% CI, 71-100%) and 80% (95% CI, 51-80%), respectively, to predict severe symptoms in the future. CONCLUSIONS The ECG is useful to distinguish ARVC children, even in the early phase. Anterior TWI and TWD could detect ARVC children and to predict the possible serious conditions.

Abstract
BACKGROUND T-wave inversion in lead III was linked to displacement of the base of the heart due to abdominal adipose tissue in early electrocardiography (ECG) trials. The observation of T-wave inversion in lead III in some of the pathological and physiological conditions other than obesity suggests the possibilities of different mechanisms. We aimed to investigate the prevalence and correlates of T-wave inversion in lead III in non-obese men. METHOD A total of 1240 men underwent ECG, blood pressure measurement, hepatic ultrasonography, and biochemical tests from January 2019 to December 2019. We excluded 220 subjects due to predetermined criteria. The eligible 105 non-obese men with T-wave inversion in lead III and 915 non-obese men without T-wave inversion in lead III were compared with each other in terms of clinical, demographic and laboratory parameters. RESULTS The mean age was 27.9 years with a range of 20 to 46 years. The prevalence of T-wave inversion in lead III was 10.3%. Body mass index (BMI), blood urea nitrogen, creatinine, alanine aminotransferase, hematocrit, and the percentage of non-alcoholic fatty liver disease (NAFLD) were significantly higher in Group with T-wave inversion while alkaline phosphatase was significantly higher in Group without T-wave inversion. In multivariable analysis, NAFLD was the best independent correlate of inverted T-wave in lead III (β = 6.215, p < 0.0001). BMI (β = 1.448, p < 0.001) and hematocrit (β = 1.179, p = 0.021) were the other independent correlates of T-wave inversion in lead III. CONCLUSION We demonstrated the association of T-wave inversion in lead III with NAFLD, BMI, and hematocrit in non-obese men.

Abstract
Apical hypertrophic cardiomyopathy is a variant of hypertrophic cardiomyopathy characterized by apical hypertrophy, deep T-wave inversions in precordial electrocardiogram (EKG) leads, and a ventriculogram shaped like the "Ace of Spades." Patients are often asymptomatic but sometimes present with atypical chest pain, angina, or atrial fibrillation. The deep T-wave inversions on EKG often mimic acute coronary syndrome. Coronary angiogram in these patients is unrevealing, but the characteristic left ventriculogram establishes this diagnosis. The deep T-wave inversions can appear suddenly or deepen over years, making the diagnosis difficult to establish early in the disease. Transthoracic echocardiogram may miss the hypertrophied apex, but echo contrast imaging or cardiac magnetic resonance imaging can reliably confirm the diagnosis and detect apical aneurysms. We present a case of apical hypertrophic cardiomyopathy which was not evident despite many admissions, EKGs, cardiac catheterizations and echocardiograms until the diagnosis was confirmed with left ventriculogram and cardiac magnetic resonance imaging 20 years after initial presentation.

Abstract
A 19-year-old patient presented with severe chest pain, which is not typical for cardiac angina. However, his smoking history and the strong family history of ischaemic heart disease coupled with evidence of progressive T-wave changes on his electrocardiogram (ECG) caused dilemma in deciding further management. His blood tests were normal apart from hypophosphataemia, and he had two negative troponin results. His arterial blood gases showed respiratory alkalosis. He was given analgesia for a diagnosis of musculoskeletal chest pain and the next morning his ECG, arterial blood gases and phosphate levels all normalised. He had a normal echocardiogram and was reviewed by the cardiologist who diagnosed musculoskeletal chest pain which led to distress and hyperventilation causing hypophosphataemia and transient T-wave inversion. This case is a reminder of an under-recognised physiological phenomenon involving the cardiac conduction during hyperventilation.

Abstract
BACKGROUND Takotsubo syndrome (TS) is a life-threatening acute heart failure syndrome. However, little is known about risk factors for worse outcomes in TS and no high-risk ECG criteria have been defined. We sought to identify ECG predictors of life-threatening in-hospital complications in TS. METHOD AND RESULT Using the nationwide Swedish Angiography and Angioplasty Registry (SCAAR) we obtained data on all consecutive patients undergoing coronary angiography at Sahlgrenska University Hospital between June 2008 and February 2019. For all patients with TS we conducted in-depth chart reviews to confirm the TS diagnosis. For those with confirmed TS we then evaluated all ECGs obtained during the index hospitalization. The primary endpoint was the occurrence of in-hospital major adverse cardiac event (MACE), defined as the composite of death, ventricular tachycardia or fibrillation (VT/VF), or atrioventricular block ≥2 or asystole ≫10 s. We identified 215 patients with TS (mean age 69 ± 13 years; 93% women). MACE occurred in 34 patients (16%), of whom 20 had VT/VF (9,3%). Patients with MACE were less likely than those without MACE to have sinus rhythm (85% versus 96%, p = 0.025) or T-wave inversion (29% versus 51%, p = 0.025). After propensity score adjustment T-wave inversion was independently associated with lower MACE risk (adjusted odds ratio [AdjOR] 0.28, 95% confidence interval [CI] 0.10-0.76, p = 0.012) and VT/VF (AdjOR 0.24, 95% CI 0.06-0.94, p = 0.041). CONCLUSION T-wave inversion is common in TS and is associated with lower risk of MACE, driven by a lower risk of VT/VF.

Abstract
BACKGROUND A variety of clinical syndromes can cause T-wave inversion (TWI), ranging from life-threatening events to benign conditions. One benign cause of TWI is cardiac memory, which is characterized by the transient inversion of T-waves following abnormal activation of the ventricles, commonly due to intermittent left bundle branch block (LBBB), tachydysrhythmias, electrical pacing, or ventricular pre-excitation. CASE REPORT A 72-year-old man presented to the emergency department with chest pain, nausea, vomiting, and headache. Upon arrival, his electrocardiogram (ECG) showed new-onset LBBB with appropriate secondary ST-T wave changes. A subsequent ECG showed disappearance of LBBB and newly inverted T-waves in precordial leads V1-V5, followed by a repeat ECG that again showed LBBB. Serial troponin testing was unremarkable. During hospitalization, echocardiogram and nuclear perfusion stress test were normal. The transient TWIs in this patient were believed to be due to cardiac memory. We performed a literature review and identified 39 published cases of cardiac memory. The most common etiology for cardiac memory was after cardiac pacemaker placement, followed by intermittent LBBB (as was seen in our patient), and post-tachydysrhythmia. Patient ages ranged from 21 to 88 years, with an equal number of cases reported in men and women. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Cardiac memory is a poorly understood, rarely observed phenomenon that can occur in the setting of intermittent LBBB. Testing for acute cardiac ischemia and underlying coronary artery disease is still recommended, as the diagnosis of cardiac memory can only be made after negative workup.

Abstract
Background Hypertrophic cardiomyopathy is one of the most common causes of sudden cardiac death in young athletes. Performing, comparing, and monitoring serial electrocardiograms over time can help to detect potential cardiovascular diseases and to prevent malignant cardiac events in these populations. Case presentation A young Han Chinese male football player had abnormal electrocardiograms for 8 years without any subjective discomfort. Electrocardiograms revealed that T-wave inversions increased from 1 mm to a maximum of 5 mm on lead I and fluctuated around 5 mm on lead avL. Q-wave duration ranged from 40 ms to 60 ms, its depth increased to a maximum of 8 mm and was much greater than 40% of the R waves in depth in II, III, and avF leads. Echocardiography showed increasingly thickened interventricular septum from 10 mm to 13 mm, enlarged left atrium and ventricle, and reduced left ventricular ejection fraction. Coronary angiography showed no distinct stenosis. Emission computed tomography revealed mild myocardial ischemia of the left ventricular inferior wall. These unusual electrocardiogram manifestations were initially regarded as benign alterations of a highly trained athlete. Upon reviewing the clinical information and the newest criteria for electrocardiographic interpretation in athletes, hypertrophic cardiomyopathy was identified. The misreading of electrocardiograms is not uncommon, thus predisposing such patients to high susceptibility to exercise-induced sudden cardiac death. Conclusions We propose that abnormal electrocardiogram findings reveal the initial expression of underlying cardiac diseases such as hypertrophic cardiomyopathy, preceding the symptoms and signs by many years. Accordingly, early detection and continuous surveillance are important for athletes with such electrocardiogram patterns, and improvement of physicians’ expertise is crucial.

Abstract
Clinical manifestation of late onset recurrent monomorphic ventricular tachycardia (VT) in patients with normal left ventricular ejection fraction may elude diagnosis despite elaborate testing. This report describes a 67-year-old woman with structurally normal heart who presented with recurrent VT in the absence of predisposing factors. Repeated extensive diagnostic testing, including magnetic resonance imaging and coronary angiography, did not disclose any abnormality. An implantable cardioverter-defibrillator was placed following noninducibility of the third episode of VT at electrophysiological study. Patient's 12-lead electrocardiogram in normal sinus rhythm revealed permanent QRS fragmentation as well as T-wave inversions as the only warning features that heralded the impending appearance of recurrent VTs over the course of 5 years follow-up.

Abstract
BACKGROUND International electrocardiographic (ECG) recommendations regard anterior T-wave inversion (ATWI) in athletes under 16 years to be normal. DESIGN The aim of this study was to identify the prevalence, distribution and determinants of TWI by ethnicity, chronological and biological age within paediatric athletes. A second aim was to establish the diagnostic accuracy of international ECG recommendations against refinement within athletes who present with ECG variants isolated to ATWI (V1-V4) using receiver operator curve analysis. Clinical context was calculated using Bayesian analysis. METHODS Four hundred and eighteen Arab and 314 black male athletes (11-18 years) were evaluated by ECG, echocardiogram and biological age (by radiological X-ray) assessment. RESULTS A total of 116 (15.8%) athletes presented with ATWI (V1-V4), of which 96 (82.8%) were observed in the absence of other ECG findings considered to be abnormal as per international recommendations for ECG interpretation in athletes; 91 (12.4%) athletes presented with ATWI confined to V1-V3, with prevalence predicted by black ethnicity (odds ratio (OR) 2.2, 95% confidence interval (CI) 1.3-3.5) and biological age under 16 years (OR 2.0, 95% CI 1.2-3.3). Of the 96 with ATWI (V1-V4) observed in the absence of other ECG findings considered to be abnormal, as per international recommendations for ECG interpretation in athletes, diagnostic accuracy was 'fail' (OR 0.47, 95% CI 0.00-1.00) for international recommendations and 'excellent' (OR 0.97, 95% CI 0.92-1.00) when governed by biological age under 16 years, providing a positive and negative likelihood ratio of 15.8 (95% CI 1.8-28.1) and 0.0 (95% CI 0.0-0.8), respectively. CONCLUSION Interpretation of ECG variants isolated with ATWI (V1-V4) using international recommendations (chronological age <16 years) warrants caution, but governance by biological age yielded an 'excellent' diagnostic accuracy. In the clinical context, the 'chance' of detecting cardiac pathology within a paediatric male athlete presenting with ATWI in the absence of other ECG findings considered to be abnormal, as per international recommendations for ECG interpretation in athletes (positive likelihood ratio 15.8), was 14.4%, whereas a negative ECG (negative likelihood ratio 0.0) was 0%.

Abstract
BACKGROUND Both Q waves and T-wave inversion (TWI) in the presenting ECG are associated with a progressed stage of myocardial infarction, possibly with less potential for myocardial salvage with reperfusion therapy. Combining the diagnostic information from the Q- and T-wave analyses could improve the prognostic work-up in ST-elevation myocardial infarction (STEMI) patients. METHODS We sought to determine the prognostic impact of Q waves and TWI in the admission ECG on patient outcome in STEMI. We formed four groups according to the presence of Q waves and/or TWI (Q+TWI+; Q-TWI+; Q+TWI-; Q-TWI-). We studied 627 all-comers with STEMI derived from two patient cohorts. RESULTS The patients with Q+TWI+ had the highest and those with Q-TWI- the lowest 30-day and one-year mortality. One-year mortality was similar between Q-TWI+ and Q+TWI-. The survival analysis showed higher early mortality in Q+TWI- but the higher late mortality in Q-TWI+ compensated for the difference at 1 year. The highest peak troponin level was found in the patients with Q+TWI-. CONCLUSION Q waves and TWI predict adverse outcome, especially if both ECG features are present. Q waves and TWI predict similar one-year mortality. Extending the ECG analysis in STEMI patients to include both Q waves and TWI improves risk stratification.

Abstract
We describe the case of a 17-year-old male soccer player with T-wave inversion in precordial leads in resting electrocardiography, which also disclosed sinus bradycardia, early repolarization, and increased QRS voltage. These findings strongly suggested cardiomyopathy. The patient's T-wave inversion disappeared during only 2 weeks of detraining, and it re-appeared 2 weeks after resumption of intensive training. This sudden change in electrocardiographic parameters over a short period helped in identifying the adolescent as having athlete's heart.

Abstract
BACKGROUND T-wave inversions (TWI) can signify serious pathology, but may also represent a benign variant. One such variant has been termed the "persistent juvenile" T-wave pattern (PJTWP). It is characterized by TWI in the right precordium, and has been understood to represent an arrested stage of the normal electrocardiographic evolution from childhood. CASE REPORT A series of four African-American (AA) women, ages 20 to 43 years, presented to the Emergency Department, and were found to have right precordial TWI that was absent on prior electrocardiograms. The diagnostic evaluation did not reveal acute cardiopulmonary causes for these new TWIs. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: The "persistent" juvenile pattern may not be actually persistent in the individual patient. In an appropriate patient, such as a young AA woman, where acute cardiopulmonary disease has been reasonably ruled out, the finding of new right precordial TWI should not preclude the diagnosis of PJTWP.

Abstract
BACKGROUND The diagnostic work-up to reveal etiology in a young ischemic stroke (IS) patient includes evaluation for high-risk source of cardioembolism (HRCE), since this subtype associates with high early recurrence rate and mortality. We investigated the association of ECG findings with a final etiologic subgroup of HRCE in a cohort of young patients with first-ever IS. METHODS The Helsinki Young Stroke Registry includes IS patients aged 15 to 49 years admitted between 1994 and 2007. Blinded to other clinical data, we analyzed a 12-lead resting ECG obtained 1-14 days after the onset of stroke symptoms in 690 patients. We then compared the ECG findings between a final diagnosis of HRCE (n=78) and other/undetermined causes (n=612). We used multivariate logistic regression to study the association between ECG parameters and HRCE. RESULTS Of our cohort (63% male), 35% showed ECG abnormality, the most common being T-wave inversion (16%), left ventricular hypertrophy (14%), prolonged P-wave (13%), and prolonged QTc (12%). 3% had atrial fibrillation (AF), and 4% P-terminal force (PTF). Of the continuous parameters, longer QRS-duration, QTc, and wider QRS-T-angle independently associated with HRCE. After AF, PTF had the strongest independent association with HRCE (odds ratio=44.32, 95% confidence interval=[10.51-186.83]), followed by a QRS-T angle >110° (8.29 [3.55-19.32]), T-wave inversion (5.06, 2.54-10.05), and prolonged QTc (3.02 [1.39-6.56]). CONCLUSION Routine ECG provides useful information for directing the work-up of a young IS patient. In addition to AF, PTF in particular showed a strong association with etiology of HRCE.

Abstract
There is increasing evidence that regular intense endurance exercise can promote structural and electrical remodeling of the right ventricle (RV). These physiological changes can be profound and are frequently accompanied by ECG changes in the right precordial leads, thereby mimicking features observed in arrhythmogenic right ventricular cardiomyopathy (ARVC). Because the 12-lead ECG is used as both a screening and diagnostic tool for the detection of conditions associated with sudden death in athletes, it is of fundamental importance to have a good understanding of the ECG features that distinguish physiological adaptations to endurance exercise from those related to RV pathology as well as their potential overlap. This article describes ECG findings observed in healthy endurance athletes versus athletes with underlying RV pathology and illustrates their differentiation using 4 case presentations.

Abstract
BACKGROUND We evaluated the prevalence of isolated T-wave inversions (TWI) in American athletes using contemporary ECG criteria. Ethnic and gender disparities including the association of isolated TWI with underlying abnormal cardiac structure are evaluated. METHODS From 2004 to 2014, 1755 collegiate athletes at a single American university underwent prospective collection of medical history, physical examination, 12-lead ECG, and 2-dimensional echocardiography. ECG analysis was performed to evaluate for isolated TWI as per contemporary ECG criteria. RESULTS The overall prevalence of isolated TWI is 1.3%. Ethnic and gender disparities are not observed in American athletes (black vs. white: 1.7% vs. 1.1%; p=0.41) (women vs. men: 1.5% vs. 1.1; p=0.52). No association was found with underlying cardiomyopathy. CONCLUSION A lower prevalence of isolated TWI in American athletes than previously reported. Isolated TWI was not associated with an abnormal echocardiogram. No ethnic or gender disparity is seen in American college athletes.

Abstract
AIM: To describe the electrocardiographic (ECG) phenomena characterized by T-wave inversion in the precordial leads in adults and to highlight its differential diagnosis.
METHODS: A retrospective chart review of 8 adult patients who were admitted with ECG T-wave inversion in the anterior chest leads with or without prolongation of corrected QT (QTc) interval. They had different clinical conditions. Each patient underwent appropriate clinical assessment including investigation for myocardial involvement. Single and multimodality non-invasive, semi-invasive and invasive diagnostic approach were used to ascertain the diagnosis. The diagnostic assessment included biochemical investigation, cardiac and abdominal ultrasound, cerebral and chest computed tomography, nuclear medicine and coronary angiography.
RESULTS: Eight adult subjects (5 females) with a mean age of 66 years (range 51 to 82) are analyzed. The etiology of T-wave inversion in the precordial leads were diverse. On admission, all patients had normal blood pressure and the ECG showed sinus rhythm. Five patients showed marked prolongation of the QTc interval. The longest QTc interval (639 ms) was found in the patient with pheochromocytoma. Giant T-wave inversion (≥ 10 mm) was found in pheochromocytoma followed by electroconvulsive therapy and finally ischemic heart disease. The deepest T-wave was measured in lead V3 (5 ×). In 3 patients presented with mild T-wave inversion (patients 1, 5 and 4 mm), the QTc interval was not prolonged (432, 409 and 424 msec), respectively.
CONCLUSION: T-wave inversion associated with or without QTc prolongation requires meticulous history taking, physical examination and tailored diagnostic modalities to reach rapid and correct diagnosis to establish appropriate therapeutic intervention.

Abstract
OBJECTIVE To investigate the predictive value of T-wave inversion (TWI) on routine electrocardiogram (ECG) for mortality in the general population with various risk groups in a prospective population-based follow-up study. Subjects. ECGs of a random population-based sample of 1814 men aged 42-60 years without coronary heart disease (CHD) at baseline. RESULTS During an average follow-up of 21 years, 685 deaths occurred. Of these deaths 174 were due to CHD and 278 to cardiovascular disease (CVD). There were 57 subjects with TWI. After adjusting for age, TWI was associated with an increased CHD mortality (relative risk (RR) 4.10, 95% CI 2.26-7.41), CVD mortality (RR 3.47, 95% CI 2.09-5.78), and all-cause mortality (RR 2.07, 95% CI 1.37-3.12). After further adjustment for conventional risk factors, TWI remained statistically significant, predicting CHD mortality (RR 2.62, 95% CI 1.57-4.36), CVD mortality (RR 2.18, 95% CI 1.40-3.38), and all-cause mortality (RR 1.41, 95% CI 1.00-2.01), respectively. CONCLUSION TWI is a strong predictor for CHD, CVD, and all-cause mortality in the general population. The respective risks of CHD and CVD among men with TWI were also increased among men with high blood pressure, LDL cholesterol, and obesity.
