Abstract
A 52-year-old male was admitted with unstable angina and three-vessel coronary artery disease. Electrocardiography (ECG) changes consistent with type-1 Brugada ECG pattern were noted during admission. The patient was asymptomatic for syncope and had no family history of sudden cardiac death, ICD implantation, and Brugada syndrome. After coronary by-pass graft the Brugada ECG pattern resolved, and ajmaline test did not elicit type-1 ECG pattern, confirming the suspicion of Brugada phenocopy.

Abstract
There is increasing literature to suggest numerous subgroups of Brugada syndrome (BrS), including those with ST elevation in the lateral or inferior leads. We present a case of a patient presenting with recurrent collapse and inferior ST elevation degenerating to ventricular fibrillation and ultimately leading to a diagnosis of BrS.

Abstract
Brugada syndrome (BrS) is characterized by coved ST segment elevation in the right precordial lead (V1-V3). Previous reports have described type-1 or type-2 Brugada ECG pattern as a Brugada phenocopy (BrP) in various clinical condition and once the etiology is resolved, the BrP ECG pattern normalizes. We describe a case report of type-1 Brugada ECG pattern in a patient with acquired immunodeficiency syndrome (AIDS) and active pulmonary tuberculosis, which developed to spontaneous pneumopericardium and pericarditis. The coexistence of type-1 Brugada ECG pattern with spontaneous pneumopericardium and pericarditis is an extremely rare pathological condition that has not been previously described.

Abstract
Brugada syndrome (BrS) is a sudden cardiac death syndrome characterized by a coved-type electrocardiogram (ECG). Different disorders, such as ischemia, can emulate a Brugada-pattern ECG (Brugada phenocopy). We report herein, the first case of surgical epicardial electrophysiological mapping in a successfully resuscitated patient with an anomalous aortic origin of the coronary artery (AAOCA) associated with a coved-type ECG. It was debatable whether the coved-type ECG and the abnormal arrhythmogenic substrate in the epicardial right ventricular outflow tract were derived from BrS or from repetitive ischemia due to AAOCA; however, the epicardial electrophysiological mapping helped in deciding the treatment strategy.

Abstract
A 71-year old male with a history of inferior myocardial infarction and hypertension underwent coronary artery bypass graft (CABG) surgery. He had no family or personal history of syncope, sudden cardiac death or Brugada syndrome. A series of twelve-lead electrocardiograms showed type 1 and type 2 Brugada ECG patterns after procedure, but resolution of ST segment changes to five days later. The electrophysiological mechanisms underlying these changes will be discussed.
