DETERMINATION OF VENTRICULAR LATE POTENTIALS IN PERSONS WITH HIGH NORMAL BLOOD PRESSURE

Authors:

Abstract:

Disturbances in the autonomic regulation of the heart are the earliest predictors of complications such as arrhythmia and sudden cardiac death against the background of high normal blood pressure. With the purpose to study the signs of myocardial electrical instability, we registered indicators of high-resolution electrocardiography. According to our results, a statistically significant difference was observed in group with high normal blood pressure for RMS40 and for the TotQRSf/RMS40 index as p<0.001 compared with healthy individuals. Between individuals with high normal blood pressure and patients from group with arterial hypertension there were significant difference for TotQRSf, RMS40 and TotQRSf/RMS40 (p<0.001) and for LAS40 (p<0.05) and statistically significant difference between patients with high normal blood pressure and arterial hypertension for TotQRSf and TotQRSf/RMS40 (p<0.001). Thus, in individuals with high normal blood pressure, electrophysiological heterogeneity is formed in the myocardium due to disturbances in the autonomic regulation of cardiac activity.
