Abstrakt: Electrophysiologic and histologic studies were performed on Langendorff-perfused human hearts from patients who underwent heart transplantation because of extensive infarction. In nine hearts, 15 sustained ventricular tachycardias could be induced by programmed stimulation. In all hearts, mapping of epicardial and endocardial electrical activity during tachycardia was carried out. Histologic examination of the infarcted area between the site of latest activation of one cycle and the site of earliest activation of the next cycle revealed zones of viable myocardial tissue.
