Registration of standard and high-resolution EGCs, echocardiography in 90 ischemic heart disease (IHD) patients on myocardial infarction week 2 to 6 has demonstrated that deterioration of local myocardial contractility and development of left ventricular dilation increase frequency of late ventricular potentials and worsen parameters of high-resolution ECG. Left ventricular dysfunction is associated with defects in autonomic regulation of cardiac activity. Diminished myocardial contractility had no significant effect on dispersion of repolarisation.
