Abstract

Conduction delay in the right ventricular outflow tract as manifested in the electrocardiogram constitutes a high-risk predictor of ventricular arrhythmias in patients with Brugada syndrome. We present a case with a right QRS axis between –90° and ±180°. This feature has never been reported in the context of Brugada syndrome. (Level of Difficulty: Advanced.)
