Prinzmetal's angina may be a rare cause of syncope and asystole even in patients with smooth coronary arteries.
May warrant considering Prinzmetal's angina in unexplained syncope with normal coronaries; leaves open generalizability of this therapy.
In a patient with proven myocardial infarction, coronary artery disease was excluded angiographically. Four weeks later the patient experienced recurrent syncope of unknown cause. By means of Holter monitoring, ST-segment elevation with subsequent first-degree AV block progressing to asystole and resulting in loss of consciousness were documented. Treatment with gallopamil and a VVI-pacemaker led to complete relief of all symptoms. Hence, Prinzmetal's angina may be a rare cause of syncope even in smooth coronary arteries.
