Time parameters of heart rate variability in patients with Stage I-II essential arterial hypertension

Abstract

In 133 patients with Stage I-II essential arterial hypertension (AH), aged 38-59 years, time parameters of heart rate variability (HRV) were compared to echocardiography data on interventricular septum thickness (IVST), left ventricular posterior wall thickness (LVPWT), LV myocardial mass index (LVMMI) and LV wall relative thickness (LVWRT). Inpatients with AH anamnesis of less than 7 years, principal HRV parameters were higher than in participants with longer AH duration. In the latter group, increased LVMMI and LVWRT were associated with reduced HRV parameters.
