title: [Late ventricular potentials and autonomic cardiac rhythm regulation in patients with acute myocardial infarction].
abstract: Relationship between late ventricular potentials (LVP) and vegetative regulation of cardiac rhythm was investigated in 52 patients with acute myocardial infarction. Using signal-averaged ECG and mathematical analysis of cardiac rhythm registered on infarction days 1, 15 and 40 it was found that by disease day 40 a direct correlation became more and more evident between inhibited ventricular activity and the intensity of sympathetic impacts on cardiac rhythm. Thus, the onset of ventricular arrhythmia in patients with myocardial infarction is resultant not only from the presence of arrhythmia substrate, but also from "the autonomic background".
