Objective The autonomic nervous system plays an important role in blood pressure
regulation and in the development of hypertension. Heart rate variability (HRV) may be of …

Aim The aim of the study was to compare heart rate variability (HRV) of newly diagnosed
essential hypertensive subjects with controls. Methods The study was conducted on 120 …

How cardiac autonomic nervous control is related to the severity of essential hypertension in
patients receiving long‐term antihypertensive therapy is not well known. The aim of this …

Background Previous studies of heart rate variability (HRV) in systemic hypertension have
yielded conflicting results. We sought to assess the alterations of HRV in hypertensive …

Background Most studies on relationships between blood pressure and autonomic nervous
function, assessed by power spectral analysis of heart rate variability, have used …

Heart rate variability (HRV) is a useful noninvasive tool to assess cardiac autonomic
function. The purpose of this study was to (1) compare measures of HRV between …

Purpose. To explore the relationship between blood pressure control and autonomic
nervous function assessing by heart rate variability (HRV) and heart rate turbulence (HRT) in …

Heart rate variability (HRV) is defined by the fluctuating time between normal sinus beats
(RR intervals) and indicates modulation of the heart rate by the autonomic nervous system …

Metabolic syndrome (MetS) is a combination of factors which, collectively, increase
cardiovascular risk to a greater extent than each of them separately. Previous studies …

Background: Autonomic nervous system (ANS) dysfunction is an important factor in the
development and progression of arterial hypertension (AH) and may produce adverse …
