Electrocardiographic Features Differentiating Arrhythmogenic Right Ventricular Cardiomyopathy From an Athlete's Heart

Abstract

Objectives: This study sought to compare electrocardiogram (ECG) variants in athletic and arrhythmogenic right ventricular cardiomyopathy (ARVC) cohorts matched for the confounders of age, sex, and ethnicity. Background: Anterior T-wave inversion (TWI V1−V4 ) is a common electrocardiographic finding in both athletes and patients with ARVC, and is a frequent conundrum in the setting of pre-participation screening. J-point elevation (JPE) has been proposed as an accurate means of identifying athletes, whereas disease markers, including premature ventricular contractions (PVCs) and low-voltage signals, have been associated with ARVC. Methods: This study examined 200 subjects with TWI V1−V4 , in..
