[ANMCO Position paper: States General 2023 - Digital medicine in cardiology: evidence and state of progress in Italy]

Technological innovation provides easily accessible tools capable of simplifying healthcare processes. Notably, digital technology application in the cardiology field can improve prognosis, reduce costs, and lead to an overall improvement in healthcare. The digitization of health data, with the use of electronic health records and of electronic health files in Italy, represents one of the fields of application of digital technologies in medicine. The 2023 States General of the Italian Association of Hospital Cardiologists (ANMCO) provided an opportunity to focus attention on the potential benefits and critical issues associated with the implementation of the aforementioned digital tools, artificial intelligence, and telecardiology. This document summarizes key aspects that emerged during the event.

[Gender discrepancy: time to implement gender-based clinical management]

It is well established that gender strongly influences cardiovascular risk factors, playing a crucial role in cardiovascular prevention, clinical pathways, diagnostic approach and treatment. Beyond the sex, which is a biological factor, gender entails a socio-cultural condition that impacts access and quality of care due to structural and institutional barriers. However, despite its great importance, this issue has not been adequately covered. Indeed sex and gender differences scarcely impact the clinical approach, creating a lot of disparities in care and outcomes of patients. Therefore, it becomes essential to increase the awareness of the importance of sex and gender influences on cardiovascular diseases. Moreover, new strategies for reducing disparities should be developed. Importantly, these differences should be taken into account in guideline recommendations. In this regard, it is crucial to include a greater number of women in clinical trials, since they are currently underrepresented. Furthermore, more women should be involved as member of international boards in order to develop recommendations and guidelines with more attention to this important topic.The aim of this ANMCO position paper is to shed light on gender differences concerning many cardiovascular drugs in order to encourage a more personalized therapeutic approach.

[ANMCO Position paper: Choosing Wisely - ANMCO proposals for 2023]

Nowadays, a progressive and exponential increase in the use of invasive and non-invasive instrumental diagnostics and therapeutic services has been shown. Although unnecessary, instrumental examinations are often largely prescribed, replacing clinical evaluation. Their correct use, on the contrary, would address precise epidemiological and clinical contexts. Therefore identifying whether a test or procedure is appropriate or not plays a crucial role in clinical practice. Several documents from scientific societies and expert groups indicate the most appropriate cardiovascular diagnostic and therapeutic procedures. The international Choosing Wisely campaign invited the main scientific societies to identify five techniques or treatments used in their field that are often unnecessary and may potentially damage patients. The Italian Association of Hospital Cardiologists (ANMCO) joined the project identifying the five cardiological practices in our country at greater risk of inappropriateness in 2014. This list has recently been updated. Moreover, possible solutions to this problem have been proposed.

ANMCO position paper on the management of hypercholesterolaemia in patients with acute coronary syndrome

Patients suffering from acute coronary syndrome (ACS) present a high risk of recurrence and new adverse cardiovascular events after hospital discharge. Elevated plasma LDL-cholesterol (LDL-C) levels have been shown to be a causal factor for the development of coronary heart disease, and robust clinical evidence has documented that LDL-C levels decrease linearly correlates with a reduction in cardiovascular events. Recent studies have also demonstrated the safety and efficacy of an early and significant reduction in LDL-C levels in patients with ACS. In this position paper, Italian Association of Hospital Cardiologists proposes a decision algorithm on early adoption of lipid-lowering strategies at hospital discharge and short-term follow-up of patients with ACS, in the light of the multiple evidence generated in recent years on the treatment of hypercholesterolaemia and the available therapeutic options, considering current reimbursement criteria.

[ANMCO Position paper: Evidence and practical indications for the use of low-dose rivaroxaban in stable coronary artery disease and peripheral artery disease]

In patients with atherosclerotic disease, the occurrence of atherothrombotic events is the main determinant of morbidity and mortality. Growing evidence suggests the involvement of the coagulation pathway in the atherosclerotic process and the benefit of antithrombotic agents, such as direct oral anticoagulants, which interfere with both platelet aggregation and the coagulation cascade. The COMPASS trial has shown that in patients with stable coronary artery disease (CAD) or peripheral artery disease (PAD), low-dose rivaroxaban (2.5 mg twice daily) added to acetylsalicylic acid (ASA) 100 mg reduces major vascular events and mortality, with an increase in major bleeding but not in fatal bleeding or involving a critical organ. The reduction in major cardiovascular events has been confirmed in the overall population with CAD and in both patients with and without a previous percutaneous coronary revascularization, and also in patients with previous coronary bypass surgery. In patients with PAD, the combination of rivaroxaban 2.5 mg twice daily and ASA was found to reduce both major adverse cardiovascular events and major adverse limb events, including major limb amputations. In clinical practice, the use of rivaroxaban 2.5 mg co-administered with ASA has been approved in both patients with CAD and symptomatic PAD at high risk of ischemic events. However, in Italy, the national health system reimbursement is provided only for patients with PAD. In patients treated with rivaroxaban 2.5 mg, assessment and monitoring of bleeding risk is crucial to achieve the maximum clinical benefit.

[ANMCO Position paper: Cardiovascular disease in women - prevention, diagnosis, treatment and organization of care]

Cardiovascular diseases are still the main cause of death among women despite the improvements in treatment and prognosis achieved in the last 30 years of research. The determinant factors and causes have not been completely identified but the role of "gender" is now recognized. It is well known that women tend to develop cardiovascular disease at an older age than men, and have a high probability of manifesting atypical symptoms not often recognized. Other factors may also co-exist in women, which may favor the onset of specific cardiac diseases such as those with a sex-specific etiology (differential effects of estrogens, pregnancy pathologies, etc.) and those with a different gender expression of specific and prevalent risk factors, inflammatory and autoimmune diseases and cancer. Whether the gender differences observed in cardiovascular outcomes are influenced by real biological differences remains a matter of debate.This ANMCO position paper aims at providing the state of the research on this topic, with particular attention to the diagnostic aspects and to care organization.

ANMCO position paper 'Appropriateness of prescribing direct oral anticoagulants in stroke and systemic thromboembolism prevention in adult patients with non-valvular atrial fibrillation'

The appropriateness of prescribing direct oral anticoagulants [dabigatran, rivaroxaban, apixaban, and edoxaban (DOACs)] is regulated on the criteria established in Phase III trials. These criteria are reported in the summary of the product characteristics of the four DOACs. In clinical practice, prescriptions are not always in compliance with established indications. In particular, the use of lower doses than those recommended in drug data sheets is not uncommon. Literature data show that the inappropriate prescription of reduced doses causes drug underexposure and up to a three-fold increase in the risk of stroke/ischaemic transient attack, systemic thromboembolism, and hospitalization. Possible causes of the deviation between the dose that should be prescribed and that prescribed in the real world include erroneous prescription, an overstated haemorrhagic risk perception, and the presence of frail and complex patients in clinical practice who were not included in pivotal trials, which makes it difficult to apply study results to the real world. For these reasons, we summarize DOAC indications and contraindications. We also suggest the appropriate use of DOACs in common clinical scenarios, in accordance with what international guidelines and national and international health regulatory bodies recommend.

ANMCO statement on the use of sodium-glucose cotransporter 2 inhibitors in patients with heart failure: a practical guide for a streamlined implementation

Sodium-glucose cotransporter 2 (SGLT2) inhibitors, dapagliflozin, and empagliflozin, first developed as glucose-lowering agents for the treatment of Type 2 diabetes, have been demonstrated to improve prognosis in patients with heart failure and reduced ejection fraction (HFrEF) regardless of the presence of diabetes. Since these drugs have only recently been included among the four pillars of HFrEF treatment, cardiologists are still unfamiliar with their use in this setting. This article provides an up-to-date practical guide for the initiation and monitoring of patients treated with SGLT2 inhibitors.

ANMCO position paper: 2022 focused update of appropriate use criteria for multimodality imaging: aortic valve disease

This document addresses the evaluation of the Appropriate Use Criteria (AUC) of multimodality imaging in the diagnosis and management of aortic valve disease. The goal of this AUC document is to provide a comprehensive resource for multimodality imaging in the context of aortic valve disease, encompassing multiple imaging modalities. Clinical scenarios are developed in a simple way to illustrate patient presentations encountered in everyday practice.

ANMCO position paper on antithrombotic treatment of patients with atrial fibrillation undergoing intracoronary stenting and/or acute coronary syndromes

Patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI) with or without acute coronary syndromes (ACS) represent a subgroup with a challenging pharmacological management. Indeed, if on the one hand, antithrombotic therapy should reduce the risk related to recurrent ischaemic events and/or stent thrombosis; on the other hand, care must be taken to avoid major bleeding events. In recent years, several trials, which overall included more than 12 000 patients, have been conducted demonstrating the safety of different therapeutic combinations of oral antiplatelet and anticoagulant agents. In the present ANMCO position paper, we propose a decision-making algorithm on antithrombotic strategies based on scientific evidence and expert consensus to be adopted in the periprocedural phase, at the time of hospital discharge, and in the long-term follow-up of patients with AF undergoing PCI with/without ACS.

[ANMCO Position paper: Care pathway for advanced heart failure patients candidate for heart transplantation/ventricular assist device]

Heart failure is a complex clinical syndrome with a severe prognosis, despite therapeutic progress. The management of the advanced stages of the syndrome is particularly complex in patients who are referred to palliative care as well as in those who are candidates for cardiac replacement therapy. For the latter group, a prompt recognition of the transition to the advanced stage as well as an early referral to the centers for cardiac replacement therapy are essential elements to ensure that patients follow the most appropriate diagnostic-therapeutic pathway. The aim of this document is to focus on the main diagnostic and therapeutic aspects related to the advanced stages of heart failure and, in particular, on the management of patients who are candidates for cardiac replacement therapy.

Update on Management of Cardiovascular Diseases in Women

Cardiovascular diseases (CVD) have a lower prevalence in women than men; although, a higher mortality rate and a poorer prognosis are more common in women. However, there is a misperception of CVD female risk since women have commonly been considered more protected so that the real threat is vastly underestimated. Consequently, female patients are more likely to be treated less aggressively, and a lower rate of diagnostic and interventional procedures is performed in women than in men. In addition, there are substantial sex differences in CVD, so different strategies are needed. This review aims to evaluate the main gender-specific approaches in CVD.

[ANMCO Position paper: Prescription appropriateness of direct oral anticoagulants for stroke and systemic thromboembolis with non-valvular atrial fibrillation]

The prescription appropriateness of direct oral anticoagulants (DOACs [dabigatran, rivaroxaban, apixaban, and edoxaban]) is carefully regulated, taking into account the criteria established in phase III trials and listed in the summary of the product characteristics of the four DOACs. In clinical practice, prescriptions are not always in compliance with established indications. In particular, the use of doses lower than those recommended in drug data sheets is relatively frequent. Literature data show that the inappropriate prescription of DOAC doses causes drug underexposure and an up to three-fold increase in the risk of stroke/transient ischemic attack, systemic thromboembolism, and hospitalizations. Possible causes of the deviation between the dose that should be prescribed and that actually employed may include erroneous prescriptions, an overstated bleeding risk perception, and the presence of frail patients, who were not included in pivotal trials. For these reasons, we summarize DOAC indications and contraindications and suggest the appropriate use of DOACs in common clinical scenarios, in accordance with what international guidelines and national and international health regulatory agencies recommend.

[ANMCO Position paper: Reorganization of cardiology in the era of the COVID-19 pandemic]

The COVID-19 pandemic represents an unprecedented event that has brought deep changes in hospital facilities with reshaping of the health system organization, revealing inadequacies of current hospital and local health systems. When the COVID-19 emergency will end, further evaluation of the national health system, new organization of acute wards, and a further evolution of the entire health system will be needed to improve care during the chronic phase of disease. Therefore, new standards for healthcare personnel, more efficient organization of hospital facilities for patients with acute illnesses, improvement of technological approaches, and better integration between hospital and territorial services should be pursued. With experience derived from the COVID-19 pandemic, new models, paradigms, interventional approaches, values and priorities should be suggested and implemented.

ANMCO POSITION PAPER: Timing of coronary angiography in non-ST-segment elevation acute coronary syndromes

The European Society of Cardiology guidelines on non-ST-elevation acute coronary syndromes suggest different temporal strategies for the angiographic study depending on the risk profile. The scientific evidence underlying the guideline recommendations and the critical issues currently existing in Italy, that often do not allow either an extended strategy of revascularization within 24 h or the application of the principle of the same day transfer from a spoke to a hub centre, are analysed. The position paper focuses, in particular, on the subgroup of patients with a defined diagnosis of non-ST-elevation myocardial infarction by proposing a timing of coronary angiography/revascularization that takes into account the available scientific evidence and the organizational possibilities of a considerable part of national cardiology services.

Non-high-density lipoprotein cholesterol versus low-density lipoprotein cholesterol in clinical practice: ANMCO position paper

Bloodstream cholesterol is a central contributor to atherosclerotic cardiovascular diseases. For several decades, low-density lipoprotein cholesterol (LDL-C) has been the main biomarker for the prediction of cardiovascular events and therapeutic target of lipid-lowering treatments. More recently, several findings have supported the greater reliability of non-high-density lipoprotein cholesterol (non-HDL-C) as a predictive factor and possible therapeutic target in refining antiatherogenic treatments, especially among patients with lower LDL-C and higher triglyceride values. This article discusses the limits of current standard methods for assessing LDL-C levels and emphasizes the persistent residual cardiovascular risk in patients treated with lipid-lowering agents on the basis of recommended LDL-C targets. It highlights that patients with controlled LDL-C and non-targeted non-HDL-C have a higher cardiovascular risk. The article focuses on the role of non-HDL-C as a better predictor of atherosclerotic disease as compared with LDL-C and as a therapeutic target. Finally, this article includes an executive summary aimed at refining preventive approaches in atherosclerotic cardiovascular disease.

[Primary aldosteronism: from diagnosis to therapy in clinical practice]

Primary aldosteronism (PA) is the single most common cause of secondary hypertension and is associated with increased target organ injury. It can be can either surgically cured or treated with targeted pharmacotherapy. PA is frequently undiagnosed and untreated, leading to aldosterone-specific cardiovascular morbidity and nephrotoxicity. Thus, clinicians should perform case detection testing for PA at least once in all patients with hypertension. The diagnostic work-up of PA is a sequence of three phases comprising screening tests, confirmatory tests and the differentiation of unilateral from bilateral forms. With appropriate surgical expertise, laparoscopic unilateral adrenalectomy is safe, efficient and curative in patients with unilateral adrenal disease. In patients who have bilateral aldosterone hypersecretion, the optimal management is a low sodium diet and lifelong treatment with a mineralocorticoid receptor antagonist administered at a dosage to maintain a high-normal serum potassium concentration without the aid of oral potassium supplements. In patients with PA, specific treatment provides prognostic benefit over optimal antihypertensive therapy and is therefore crucial to reduce mortality and morbidity in this subgroup of patients with hypertension.

Updated clinical evidence and place in therapy of bempedoic acid for hypercholesterolemia: ANMCO position paper

The central role of high low-density lipoprotein cholesterol levels in atherosclerotic cardiovascular disease has led to research focused on lipid-lowering agents for cardiovascular risk reduction. Bempedoic acid is an emerging treatment for hypercholesterolemia that has recently been approved for marketing in the United States and Europe. This review focuses on its mechanism of action and summarizes the main preclinical study findings. Furthermore, we report the clinical evidence supporting and guiding its use in hypercholesterolemia management.

[HCF-ANMCO/AICPR/GIEC/ITAHFA/SICOA/SICP/SIMG/SIT Cardiological Societies Council Consensus document: Anticoagulant therapy in venous thromboembolism and atrial fibrillation of the patient with cancer. Current knowledge and new evidence]

Venous thromboembolism (VTE), including pulmonary embolism and deep venous thrombosis, either symptomatic or incidental, is a common complication in the history of cancer disease. The risk of VTE is 4-7-fold higher in oncology patients, and it represents the second leading cause of death, after cancer itself. In cancer patients, compared with the general population, VTE therapy is associated with higher rates of recurrent thrombosis and/or major bleeding. The need for treatment of VTE in patients with cancer is a challenge for the clinician because of the multiplicity of types of cancer, the disease stage and the imbricated cancer treatment. Historically, in cancer patients, low molecular weight heparins have been preferred for treatment of VTE. More recently, in large randomized clinical trials, direct oral anticoagulants (DOACs) demonstrated to reduce the risk of VTE. However, in the "real life", uncertainties remain on the use of DOACs, especially for the bleeding risk in patients with gastrointestinal cancers and the potential drug-to-drug interactions with specific anticancer therapies.In cancer patients, atrial fibrillation can arise as a perioperative complication or for the side effect of some chemotherapy agents, as well as a consequence of some associated risk factors, including cancer itself. The current clinical scores for predicting thrombotic events (CHA2DS2-VASc) or for predicting bleeding (HAS-BLED), used to guide antithrombotic therapy in the general population, have not yet been validated in cancer patients. Encouraging data for DOAC prescription in patients with atrial fibrillation and cancer are emerging: recent post-hoc analysis showed safety and efficacy of DOACs for the prevention of embolic events compared to warfarin in cancer patients. Currently, anticoagulant therapy of cancer patients should be individualized with multidisciplinary follow-up and frequent reassessment. This consensus document represents an advanced state of the art on the subject and provides useful notes on clinical practice.

ANMCO POSITION PAPER: Considerations on in-hospital cardiological consultations and cardiology outpatient clinics during the COVID-19 pandemic

Infections by SARS CoV2 - COVID-19 have become in a short time a worldwide health emergency. Due to cardiovascular implications of COVID-19 and to very frequent previous cardiovascular disorders of COVID-19 patients, it is presently crucial that Cardiologists are fully aware of COVID-19 related epidemiological, pathophysiological and therapeutic problems, in order to manage at best the present emergency by appropriate protocols developed on the basis of the competences acquired and shared on the field. The aim of this document is to propose algorithms for the management of cardiovascular diseases during COVID-19 emergency with the objective of providing patients with optimal care, minimizing contagion risk and appropriately managing personal protective equipment.

ANMCO POSITION PAPER: Network Organization for the Treatment of Acute Coronary Syndrome Patients during the Emergency COVID-19 Pandemic

The COVID-19 pandemic has become a global health emergency. In Italy, the number of people infected by SARS-COVID-2 is rapidly increasing and what emerges from the current data is that the majority do not present any symptoms or only minor flu-like symptoms. In about 20% of the patients, the disease progresses towards more complex forms (interstitial pneumonia to acute respiratory distress and multiple organ failure) with the need of hospitalization in CICU and advanced ventilator assistance. The transmission of the virus occurs very easily from the symptomatic patient s droplets from coughing and sneezing and from direct contact with persons or surfaces. In a patient presenting with ST elevation (STEMI) myocardial infarction or STEMI-like, if positive to COVID-19, the reperfusion therapeutic strategy depends on the local organization and on the possibility to access without delay a PCI COVID Center, on the basis, obviously, of the risk/benefit assessment of the individual case. However, we advise to try pursuing, in the first instance, the mechanical revascularization strategy, according to the available local possibilities.

ANMCO POSITION PAPER: The management of suspect or confirmed COVID-19 patients needing urgent electrophysiology and/or electrostimulation procedures

The aim of this document is the management and organization of patients in need of urgent access to electrophysiology (EP) and pacing procedures during the COVID-19 emergency. Specifically, non-deferrable procedures or irreplaceable with a drug therapy prior to the resolution of the COVID-19 virus emergency [pacemaker (PM) implant/replacement/urgent defibrillator (implantable cardioverter-defibrillator, ICD) or arrhythmic storm or other indication of non-deferrable ablation]. The pacing and electrophysiological procedures urgent as they may be, less and less frequently represent situations of emergency, therefore for almost all cases, it is possible to perform a swab test to determine the positivity to COVID-19 of the patient. In cases where this is not possible, due to situations of emergency, the recommendations and procedures we have indicated are advisable, if not mandatory, in order to avoid the spreading of the virus to healthcare personnel and other patients.

ANMCO POSITION PAPER: The role of cardiology in the management of the health needs in the post-Covid-19 era

At the end of 2019 a new Coronavirus appeared in China and, from there, it spread to the rest of the world. On 24th May, 2020, the confirmed cases in the world were more than 5 million and the deaths almost 350.000. At the end of May, Italy reported more than 27.000 cases among healthcare professionals and 163 deaths among physicians. The National Health Systems from almost all over the world, including Italy's, were unprepared for this pandemic, and this generated important consequences of organizational nature. All elective and urgent specialized activities were completely reorganized, and many hospital units were partially or completely converted to the care of the COVID-19 patients. A significant reduction in hospital admissions for acute heart disease were recorded during the SARS-CoV-2 pandemic and, in order to gradually resume hospital activities, the Italian National Phase 2 Plan for the partial recovery of activities, must necessarily be associated with a Phase 2 Health Plan. In regards to the cardiac outpatient activities we need to identify short term goals, i.e. reschedule the suspended outpatient activities, revise the waiting lists, review the 'timings' of the bookings. This will reduce the number of available examinations compared to the pre-Covid-19 era. The GP's collaboration could represent an important resource, a structured telephone follow-up plan is advisable with the nursing staff's involvement. It is equally important to set medium-long term goals, the pandemic could be an appropriate moment for making a virtue of necessity. It is time to reason on prescriptive appropriateness, telemedicine implementation intended as integration to the traditional management. It is time to restructure the cardiological units related to the issue of structural adjustment to the needs for functional isolation. Moreover, the creation of 'grey zones' with multidisciplinary management according to the intensity of care levels seems to be necessary as well as the identification of Covid dedicated cardiologies. Finally, the pandemic could represent the opportunity for a permanent renovation of the cardiological and territorial medicine activities.

[ANMCO Position paper: From acute to chronic disease: the needs of complex cardiac patients]

Managing a patient suffering from a chronic disease requires a multidisciplinary team that can take care of them beyond the simple coordination of various specialties. In this context, a central role in the treatment of chronic heart disease is the continuity of care that should promote organic integration among different hospital departments, hospital and community. This position paper of the Italian Association of Hospital Cardiologists (ANMCO) aims at defining the general principles to inspire care for complex cardiac patients at different phases of the disease. A multidisciplinary integrated holistic approach uses analytical tools able to understand the elements that characterize complexity and therefore suggest appropriate management strategies: (i) care pathways aimed at optimizing treatments; (ii) care pathways in intensive care and ward in a multidisciplinary perspective; (iii) integration of social and health needs; (iv) nursing role in the context of continuity of outpatient, community and home care; (v) promotion of educational interventions.

Remote monitoring: Doomed to let down or an attractive promise?

Device interrogation and management are time consuming, representing a relevant burden for pacing centers. In several situations, patients' management requires additional follow up visits.

Remote Monitoring (RM) allows an optimal recall management and a rapid diagnosis of device or lead failure, without the need of additional in office visits. Further it allows a significant delay reduction between the adverse event and the reaction to the alarm, shortening the time needed to make a clinical decision. A role in risk-predicting patient-related outcomes has also been shown. RM permits detection of the arrhythmia from 1 to 5 months in advance compared to in-office visits. Importantly, by using specific algorithms with multiparametric analysis, RM has been studied as a potential instrument to identify early patients on risk of worsening HF using specific algorithms. Although the use of RM in HF setting remains controversial, it has been proposed to improve HF clinical outcomes and survival in clinical trials. In this sense, RM success could require a standardization of process within a management model, that may involve different health care professionals. In this review, we examine recent advances of RM providing an update of this tool through different clinical scenarios.

Rate-responsive pacing regulated by cardiac haemodynamics

AIMS

Trans-valvular impedance (TVI) recording has been proposed for the assessment of cardiac haemodynamics, assuming an inverse relationship between TVI and ventricular volume. We checked whether the TVI sensor can drive the rate-responsive function of a cardiac pacemaker following changes in the inotropic regulation of the heart.

METHODS

An external DDD-R pacemaker (Ext Sophos by Medico, Padova, Italy) equipped with the TVI detecting system was tested in 30 patients on the implantation of conventional pacing leads for dual-chamber pacing. Pacing rate regulation was based on the relationship between the stroke volume and the end-diastolic volume, inferred from TVI data. After sensor calibration in basal conditions, beta-adrenergic stimulation was induced by i.v. administration of 2 microg/ml/min isoprenaline (isoproterenol) (IPN). The actual cardiac rate, the TVI waveform, the end-diastolic and systolic TVI in each cardiac cycle and the TVI-indicated rate were stored in memory as a function of time and down-loaded at the end of the session.

RESULTS

All patients with intrinsic atrial activity (28/30) showed a positive chronotropic response to IPN, coupled with a significant increase in end-diastolic TVI and a four-times larger increase in end-systolic TVI. The TVI inotropic index mirrored the sinus rate time-course, with a linear correlation between the two parameters (r(2)>0.7 in 25/28 cases). As a result, the TVI-indicated rate closely reproduced the sinus rate.

CONCLUSIONS

The study confirms the reliability of the haemodynamic information derived from TVI and supports its application in the regulation of rate-responsive pacing.
