title: [Electrocardiographic findings typical of Brugada syndrome unmasked by cocaine consumption].
abstract: Brugada syndrome is characterized by the presence of right bundle branch block on electrocardiography and by ST-segment elevation in the right precordial leads (V1-V3), by the absence of structural cardiac abnormalities, and by episodes of syncope or sudden death. On occasion, diagnosis is made difficult by temporary normalization of the ECG. The condition can be unmasked by potent sodium channel blockers, such as flecainide. Our patient presented with a Brugada syndrome-type ECG after intake of a large amount of cocaine.
