[Isolated and asymptomatic Brugada syndrome. A case report].

The case report of a 32-year-old man with a Brugada syndrome is presented. He was asymptomatic and without familial history of sudden death or syncope. Diagnosis criteria for Brugada syndrome were 1--a pattern of right bundle branch block and ST-segment elevation in leads V1 and V2 on the ECG, 2--no cardiac structural anomalies. Symptomatic patients with this electrical anomaly are at high risk of sudden death and need an automatic implantable defibrillator. The outcome and the treatment of asymptomatic patients are a matter of debate and are discussed in this report.
