Arrhythmogenic right ventricular cardiomyopathy arvc also known as arrhythmogenic right ventricular dysplasia is a heart muscle disease clinically characterized by life threatening ventricular arrhythmias and pathologically by an acquired and progressive dystrophy of the ventricular myocardium with fibrous or fibro fatty replacement 1 2 3. Prospective evaluation of relatives for familial arrhythmogenic right ventricular cardiomyopathy dysplasia reveals a need to broaden diagnostic criteria. These abnormalities include inverted t waves beyond lead v 1 in young males the presence of right bundle branch block the presence of an epsilon wave and the presence of right ventricular outflow tract ventricular tachycardia with a left bundle branch block pattern.

The classic ecg findings in arrhythmogenic right ventricular dysplasia are inverted t waves in the right precordial leads v1 v3 with an epsilon wave just after the qrs in lead v1. 1 anterior t wave inversion in the right precordial leads v1 v3 present in 85 and 2 ε waves present in 33 of arvc patients. ε waves are reproducible low amplitude signals occurring after the end of qrs complex and before the t wave in the right precordial leads.
