Wide Complex Tachycardia

Abstract

Supraventricular tachycardia with aberrancy and ventricular tachycardia can often be differentiated on the basis of subtle findings. We present an electrocardiogram with findings of Coumel’s sign, which is diagnostic of atrioventricular re-entrant tachycardia using an accessory pathway. (Level of Difficulty: Advanced.)
