Rhabdomyoma of the interventricular septum presenting as a Brugada phenocopy

Abstract

AbstractBrugada syndrome is a channelopathy characterised electrocardiographically by distinctive coved ST-segment elevation in the right precordial leads and is associated with a predisposition for sudden death secondary to ventricular arrhythmias in otherwise healthy patients. Previously known as Brugada-like patterns, Brugada phenocopies include agents and conditions that mimic true Brugada syndrome, presenting with an acquired Brugada Type-1 ECG pattern. We describe the first reported case of a 17-month-old female with an asymptomatic rhabdomyoma of the interventricular septum that presented as a Brugada phenocopy.
