Two patients with lifethreatening episodes of ventricular fibrillation (VF) showed typical ST elevation in V1V3 leads. Both had spontaneous clinical episodes of resting angina. Intracoronary injection of acetylcholine provoked coronary vasospasm and ST elevation was the same as Brugadatype ST elevation in 1 case but not in the other. Calcium channel antagonist was prescribed to prevent coronary vasospasm but Brugadatype ST elevation and the occurrence of VF could not be prevented. The symptoms accompanied both cases. Considering these cases, the pathogenesis of Brugada syndrome should differ from that of coronary vasospasm because it could not be prevented by calcium channel antagonist.
