Incessant ventricular tachycardia complicating acute myocardial infarction: treatment by map-guided infarctectomy.

A 58-year-old man developed incessant ventricular tachycardia on the fourth and fifth days following acute anterior myocardial infarction. The tachycardia was resistant to antiarrhythmic drugs, cardioversion and pacing. Preoperative and intraoperative mapping suggested a subendocardial origin, and successful infarctectomy was performed on the fifth day of the infarction.
