ST-segment elevation after direct current shock mimicking acute myocardial infarction: a case report and review of the literature.

Abstract
External direct current (DC) shocks are and have long been commonly used for electrical cardioversion/defibrillation of atrial or ventricular arrhythmias. ST-segment elevation after cardio version with DC is an easily ignored phenomenon, occurring acutely and resolving during the first few minutes postshock. Here, we describe electrocardiographic findings of widespread ST-segment elevation lasting at least 1 hour after DC cardioversion for ventricular defibrillation due to Brugada syndrome and mimicking acute myocardial infarction (AMI). This case of ST-segment elevation without a dynamic and evolving AMI underscores the need to consider other causes of ST-segment elevation.
