Perez diez d brugada j. Michael gibson m s m d. Arrhythmogenic right ventricular dysplasia arvd which was first described in 1977 is a poorly understood yet potentially lethal cause of cardiac disease 1 2 once thought to be rare arvd has. J am coll cardiol 2002 40 1445 1450.

An article from the e journal of the esc council for cardiology practice european society of cardiology 2008. Arrhythmogenic right ventricular dysplasia arvd is a cardiomyopathy characterized by fibrofatty infiltration of the right ventricular rv wall which often leads to ventricular arrhythmias rv dilation and dysfunction and ultimately may lead to rv failure this condition often appears in young adulthood appears to be more common in men and affected individuals may be asymptomatic or. Arrhythmogenic right ventricular dysplasia cardiomyopathy. Arrhythmogenic right ventricular dysplasia.

Arvc is defined by the gradual loss of myocardial cells which are replaced by fat and fibrous tissue. Thirty five patients with arrhythmogenic right ventricular dysplasia cardiomyopathy underwent serial electrocardiographic ecg testing and were evaluated for evidence of ecg progression. Prospective evaluation of relatives for familial arrhythmogenic right ventricular cardiomyopathy dysplasia reveals a need to broaden diagnostic criteria. The ecg illustrates the typical findings in arvc.

ε waves are reproducible low amplitude signals occurring after the end of qrs complex and before the t wave in the right precordial leads. 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. 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. An ekg abnormality is present in 90 of patients with avrd.

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. 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. Screening diagnosis and treatment. Arrhythmogenic right ventricular cardiomyopathy dysplasia arvc arvd arrhythmogenic right ventricular cardiomyopathy arvc is considered a genetic cardiomyopathy that predominantly affects the right ventricle.

Over a median of 43 months 89 of the patients had evidence of progression with s wave prolongation being the.
