Arrhythmogenic Cardiomyopathy

On this page:Diagnosis


Arrhythmogenic right ventricular dysplasia (ARVD) is an inherited disorder in which there is fibro-fatty replacement of the right ventricular myocardium. The condition is the second most common of sudden cardiac death in young people.


The most classic ECG finding in ARVD is epsilon waves. Patients with ARVD may develop ventricular tachycardia, which is of right ventricular origin (with left bundle branch morphology).
  • ECG Findings in ARVD

  • Epsilon wave - a small upward deflection in leads V1-V3
  • T wave inversion in leads V1-V3
  • Localised QRS widening in leads V1-V3
  • Ventricular tachycardia with left bundle branch morphology
  • Diagnosis
