摘要篇首： Idiopathic ventricular fibrillation (VF) has been reported to account for 3%-9% of all sudden arrhythmic deaths.1 In 1991, Pedro and Josep Brugada first described a subgroup of patients with idiopathic VF who presented with a right bundle branch block (RBBB) pattern and marked ST-segment elevation in the right precordial leads V1-V3 during sinus rhythm in the absence of any structural heart disease.2 This is now known as the Brugada syndrome. In Hong Kong the first two cases of Brugada syndrome were reported in April 1999 in local medical literature. Since then more patients from different local hospitals were identified to suffer from the syndrome. We report here a male patient suffering from Brugada syndrome which masqueraded as an acute anteroseptal myocardial infarction 10 years ago.
