The aim of research was comparison of prognostic importance of various indexs non-homogeneousness of processes repolari-zations of heart ventricles registered in acute and subacute periods of myocardial infarction (MI). The retrospective analysis of med-ical histories has allowed to determine dynamics of dispersion of intervals Q-T, Q-Ta and R-Tm in groups of patients with fa-vourable ( n = 125) and lethal ( n = 250) outcome. The best prognostic importance concerning fatal cardial events have indexs cor-rected on frequency of cardiac rhythm. Most important and independent predictor of intrahospital cardial deaths of the patients with MI is a dispersion of the corrected interval R-Tm, exceeding 80 мс1/2 in the first 6 hours after hospitalization.
