Resistant ventricular tachycardias and recurrent cardiac arrests. 96 episodes

A 66-year-old man suffered an acute myocardial infarction complicated by multiple episodes of ventricular tachycardia and 96 episodes of ventricular fibrillation requiring cardioversion over a period of 55 days. Following ventricular aneurysmectomy, the ventricular tachycardia persisted. This converted to regular sinus rhythm with a regimen of disopyramide phosphate, quinidine, and propranolol.
