[Severe persistent sub-shift of the ST segment following cardioversion in ventricular tachycardia]

The authors report a case of severe ST elevation after defibrillation which persisted for 6 days, suggesting acute myocardial infarction. The possible mechanisms of ST elevation after cardioversion and the unusually long duration of the ECG changes in this case are reviewed. The protective role of verapamil against myocardial damage is discussed.
