“…We propose the following interpretations for these findings: the NR area indicates the central portion of a large infarction, which was almost unexcitable scar; the peri-NR area delay, crowds of isochrone lines, and islandlike zones of delayed activation indicate the area of partial or small infarction, where excitation propagated slowly through the surviving myocardial cell. These hypotheses agree closely with the results of Durrer et al 19 on epicardial and intramural ECGs in experimental chronic myocardial infarction. They concluded that QS complexes on epicardium were present only where the infarction was transmural.…”

“…Twenty-one of 50 patients (58%) had abnormal RMS voltage of less than 20 ,V (upper limit of normal for our laboratory). The duration of the signal-averaged QRS vector complex ranged from 91 msec to 144.5 msec (mean 1 to 30 days (mean 1 1 + 9 days) after the signal-averaging procedure; in six patients the ventricular arrhythmias occurred 1 to 3 days (mean 2.0 ± 1.0 days) before the procedure and in two ventricular arrhythmias were noted on the day of the procedure. In 12 of the 19 patients (63%) the ventricular arrhythmias were noted after the first 3 days of AMI, whereas in the remaining seven patients (37%) arrhythmias were noted within the first 3 days after AMI.…”

“…Animal studies have shown that ischemic myocardial tissue will be depolarized later than normal perfused myocardium (Baschieri et al, 1967;Durrer et al, 1964; El-Sherif et af., I977a,b). Such fractionated and delayed electrical activity of ventricular myocardium will appear within the ST segment of the electrocardiogram and has been related to ventricular re-entry dysrhythmias.…”
