Abstract
Concepts of ventricular tachycardia (VT) have markedly changed in the last 10 yr, with the help of sophisticated electrophysiological methods of study. The importance of the reentry phenomenon in the mechanism of this arrhythmia was pointed out by stimulation procedures. Epicardial mapping allowed localization of the abnormal zone where delayed impulses could allow reentry. Surgical techniques were developed from these observations to prevent reentrant VT in some refractory cases.
