[Cardiac arrest caused by coronary arterial vasospasm].

Coronary arterial vasospasm may be associated with acute myocardial infarction, ventricular tachycardia or fibrillation as well as sudden death. Two case reports describing coronary vasospasm leading to ST-segment elevation and cardiac arrest are presented. Coronary arteriography revealed an occlusion that disappeared after injection of nitroglycerine. Both patients were treated with calcium antagonists and a cardioverter defibrillator (ICD) was implanted. One year after the ICD implantation no tachyarrhythmias had been registered.
