Background. The authors studied electrophysiological indices and structural-functional parameters of the heart in patients with diastolic heart failure at diabetes mellitus type 2 (DM2).
Methods and materials. The researchers observed 128 patients (56 men and 72 women) with the average age of 59.9 ± 7.4 years. Besides the standard clinical re-search, the authors performed a whole complex of work including electrocardiogra-phy in 12 derivations, echocardiography, Holter monitoring, registration of average-signal electrocardiography with identification of ventricular delayed potential, analy-sis of variability of cardiac rhythm, evaluation of ventricle repolarization - interval dispersion Q-T (QTd), resolved interval Q-T (QTC).
Results. At diastolic dysfunction of the left ventricular by a restrictive type the ventricular delayed potentials were diagnosed in 72,4 % of patients; the researchers registered high incidence of complex forms of ventricular arrhythmias: ventricular premature beats IV-V grades (48,3 %) and III grade (34,5 %).
Conclusions. The study showed a strong correlation between the diastolic func-tion of the left ventricle and the indicators of electrical remodeling of the myocar-dium.
