Prevalence and prognosis of ventricular tachycardia/ventricular fibrillation in patients with post-infarction left ventricular aneurysm: Analysis of 575 cases
We investigated the prevalence of ventricular tachycardia/ventricular fibrillation (VT/VF) in Post-infarction left ventricular aneurysm (PI-LVA) patients and analyze clinical outcomes in patients presenting with VT/VF. (Source: Journal of Electrocardiology)

A novel three base-pair deletion in domain two of the cardiac sodium channel causes Brugada syndrome
Mutations within SCN5A are found in a significant proportion (15 –30%) of Brugada syndrome (BrS) cases and impair sodium transport across excitable cardiac cells that mediate ventricular contractions. Genetic testing offers a means to clinically assess and manage affected individuals and their family members. (Source: Journal of Electrocardiology)

A case of narrow complex bigeminy, what is the underlying rhythm?
Narrow complex bigeminy is a common electrocardraphic finding that can be caused by second degree sinoatrial exit block or ectopic atrial bigeminy. These rhythms can be very challenging to distinguish on a 12-lead electrocardiogram. In this case of an elderly woman who presented with narrow complex bigeminy, we review the differentiating features of second degree sinoatrial exit block and ectopic atrial bigeminy.

Letter to the editor: Is “triangular QRS-ST-T waveform” a left main total occlusion marker?
We have read with great interest the article by Cipriani et al. [1] concerning the incidence and clinical implication of a special ECG pattern that they have called “triangular QRS-ST-T waveform” (TW). They observed that patients with ST-segment elevation acute myocardial infarction (STEMI) and TW had a higher risk of ventricular fibrillation, cardiogenic shock and in-hospital mortality. Furthermore, patients with TW pattern significantly more often showed a left main coronary artery (LMCA) involvement (2/4, 50% vs 2/322, 0.6%; p (Source: Journal of Electrocardiology)

Brugada Phenocopy induced by recurrent hyperkalemia: More evidence for the reproducibility of a new phenomenon
We present a case of a patient with recurrent Brugada-like ST-segment elevation induced by hyperkalemia. To the best of our knowledge, this is the first case of reproducible hyperkalemia-induced BrP to be reported. (Source: Journal of Electrocardiology)

High-grade atrioventricular block in patients with acute myocardial infarction. Insights from a contemporary multi-center survey
High-grade atrioventricular block (HAVB) is a frequent complication of acute myocardial infarction (AMI) and is associated with increased morbidity and mortality. We aimed to evaluate the incidence, predictors, and prognostic significance of HAVB in a contemporary cohort of patients with AMI, in the recent era of early reperfusion. Patients with acute coronary syndromes (n=11,487) during the years 2000 –2010 were included. Patients were divided into two groups: with HAVB (n=308, 2.7%) and without HAVB (n=11,179, 97.3%).

Meta-analysis of Tpeak –Tend and Tpeak–Tend/QT ratio for risk stratification in congenital long QT syndrome
Congenital long QT syndrome (LQTS) predisposes affected individuals to ventricular tachycardia/fibrillation (VF/VF), potentially resulting in sudden cardiac death. The Tpeak –Tend interval and the Tpeak–Tend/QT ratio, electrocardiographic markers of dispersion of ventricular repolarization, were proposed for risk stratification but their predictive values in LQTS have been controversial. A systematic review and meta-analysis was conducted to examine the value of Tpe ak–Tend intervals and Tpeak–Tend/QT ratios in predicting arrhythmic and mortality outcomes in congenital LQTS.

Recognising the de Winter ECG pattern – A time critical electrocardiographic diagnosis in the Emergency Department
We present a case of a patient who attended our Emergency Department with chest pain and a prehospital ECG demonstrating transient infero-lateral lead ST segment elevation, which changed to the de Winter ECG pattern in our Emergency Department. She subsequently underwent primary PCI of the culprit lesion within the left anterior descending artery (LAD). (Source: Journal of Electrocardiology)
