The study of predictors of the development of arrhythmia in elderly age people with IHD is an important task requiring the thorough investigation. The presence of late potentials of ventricles (LPV) is considered presently as one of the most highly informative parameters indicating an electrical inhomogeneity of myocardium, which would result in cardiac rhythm disturbance. The presence of early, late ventricle potentials as well as a dispersion of QT, QRS and T intervals are believed to be the predictors of arrhythmia along with other indices. The study focused on determining a frequency of such predictors among patients of 60 - 74 y. o. with various clinical picture of IHD. 300 patients were observed: 120 of them with IHD, 100 - additionally having essential hypertension, 60 - PICS (postinfarction cardiosclerosis), 20 - HF. 20 people aged 60 - 89 formed the control group. The registration of LPV, EPV as well as QT, QRS and T dispersion was carried out by means of Megacart electrocardiograph (produced by "Siemens" company, Germany). The findings are the following: 48 % of the patients with IHD were found with LPV, 33 % - with EPV (early potentials of ventricles). LPV is also more frequently met in the patients with IHD complicated with heart failure (HF) and hypertension; dispersion of QRS and T is for sure higher in patients with IHD and HF.
