title: The presence of epsilon waves in all precordial leads (V1 -V6 ) in a 13-year-old boy with arrhythmogenic right ventricular dysplasia (ARVD).
abstract: Electrocardiographic feature is included in the diagnostic criteria for arrhythmogenic right ventricular dysplasia (ARVD) based on the Revised Task Force criteria 2010. The epsilon wave, which reflects delayed conduction of the right ventricle, is considered to be one of the major diagnostic criteria. We reported a 13-year-old Thai boy with ARVD who presented with ventricular tachycardia. The presence of epsilon wave in all precordial leads (V1 -V6 ) was observed in standard 12-lead EKG. Extensive scarring of the right and left ventricle was seen on cardiac MRI. The extensive Epsilon wave found in this patient may reflect the extensive ventricular wall involvement.
