title: [Clinical and prognostic significance of the degree of delayed ventricular function and vegetative regulation of cardiac rhythm in myocardial infarction patients].
abstract: Ventricular tachyarrhythmias (VT) are responsible for many sudden deaths in postmyocardial infarction (PMI) patients. The aim of the study was to investigate clinical and prognostic significance for such patients of delayed ventricular activity and vegetative regulation of cardiac rhythm. Signal-averaged ECG, mathematical analysis of cardiac rhythm with measurement of variation range, mode, index of regulatory systems tension, 24-h ECG monitoring were made in 90 patients with acute large-focal myocardial infarction (MI) on the disease day 1, 15, 40 and 365. Signal-averaged ECG registered on MI day 15 was found most informative for identifying the risk to develop VT. Combined application of diagnostic techniques brings more information than each of them alone.
