Deaths due to coronary accidents during or following electroconvulsive therapy (ECT) have been repeatedly reported. The connection between ECT and these deaths could only be presumptive. Our patient suffered a myocardial infarction during his first ECT and a fatal acute coronary insufficiency during his second ECT, given three months later. These two incidents together strongly suggest that ECT may trigger coronary death in persons with significant coronary heart disease.
