Myocardial infarction is an uncommon complication of electroconvulsive therapy. Because of this, in spite of the existence in psychiatric literature of some studies about this question, the knowledge in this regard by most cardiologists is scarce. We present a patient with an acute myocardial infarction after the application of a electroconvulsive therapy. In the end, we accomplish review of the literature in relation to incidence, physiology, prevention and indication or not of fibrinolytic drugs in acute myocardial infarction after electroconvulsive therapy.
