Arrythmogenic Right Ventricular Dysplasia (ARVD)


  • genetic disease of desmosome dysfunction resulting in the progressive replacement of the RV myocardium by fatty fibrous tissue which slows cardiac impulse conduction through the RV
  • may account for 3-5% of sudden cardiac death under the age of 65 years as it may cause exercise or catecholamine-induced Right Ventricular Outflow Tract Tachycardia (RVOT) and ventricular fibrillation (VF), while survivors often develop RV failure

ECG findings

  • Epsilon wave - a small positive deflection at the very end of the QRS complex
  • T wave inversion in V1-3
  • localized QRS widening and prolonged S-wave upstroke in V1-V3
