Evaluation of heart rate variability using 24-hour Holter electrocardiography in hypertensive patients.

ABSTRACT:

Background

Hypertension (HTN) remains a serious risk factor for cardiovascular mortality across the world. Hypertensive state has been shown to be associated with autonomic nervous function. This study aimed to explore the association between autonomic nervous impairment assessed by heart rate variability (HRV) and HTN.

Methods

A total of 52 hypertensive and 55 non-hypertensive patients were consecutively studied using 24-hour Holter. The hypertensive patients were grouped into controlled blood pressure (BP) and uncontrolled BP. This study compared HRV in non-hypertensive and hypertensive patients; and hypertensive patients with controlled and uncontrolled BP. HRV parameters include time and frequency domain.

Results

Mean age for hypertensive and non-hypertensive pati
