We report the case of a patient with genetically confirmed Brugada syndrome who presented with ST-segment elevation in the right precordial and inferior leads. The presenting arrhythmia was atrial fibrillation, which degenerated into ventricular fibrillation during intravenous amiodarone. A flecainide test was markedly positive. Four appropriate cardioverter-defibrillator discharges occurred during a two-year follow-up period after implantation of the device.
