The pathophysiological mechanism underlying Brugada syndrome: depolarization versus repolarization.
This Point/Counterpoint presents a scholarly debate of the mechanisms underlying the electrocardiographic and arrhythmic manifestations of Brugada syndrome (BrS), exploring in detail the available evidence in support of the repolarization vs. depolarization hypothesis.
متن کاملAn update on early repolarization(ER) syndrome
Early repolarization (ER), also known ‘J-waves’ or ‘J-point elevation’, is an electrocardiographic abnormality consistent with elevation of the junction between the end of the QRS complex and the beginning of the ST segment in 2 contiguous leads. Many studies have shown that the ER ECG pattern is a sign of increased mortality. In this issue of the EP update, we have summarized the recent resear...
متن کاملEarly repolarization syndrome: a decade of progress.
Stemming back to the days of Einthoven, ECG phenomena of “early ventricular repolarization” were often misinterpreted or dismissed without appropriate clinical consideration or detailed investigation. This ensued because of a prevailing opinion that the nature of these phenomena was largely "benign". Early repolarization changes consistent with Brugada Syndrome (BrS) were interpreted as "innoce...

متن کاملEvaluation Of Patients With Early Repolarization Syndrome.
In recent years, the early repolarization pattern has emerged as a risk factor for malignant ventricular arrhythmias and sudden cardiac death. The identification of the subset of patients who are at high risk of sudden death represents a significant challenge to the clinician. Multiple clinical and ECG features have been associated with an increased risk of sudden deathin however the majority o...
