Abstract
Hypertensive patients are characterized by decreased values of the heart rate variability (HRV) components related
to vagal activity. A reduction in parasympathetic activity significantly contributes to a disturbance in sympathetic and
parasympathetic cardiovascular control in hypertension.
The balance in autonomic control mechanisms is shifted
towards a preponderance of sympathetic efferent activity.
Also the circadian rhythm of HRV components dependent
on sympathetic and parasympathetic activity is altered in
essential hypertension.
Heart rate variability is significantly reduced in patients with
left ventricular hypertrophy secondary to hypertension. Left
ventricular mass seems to be the most important determinant of the sympathovagal imbalance in hypertensive patients.
Changes in HRV in patients with essential hypertension
reflect disturbances in cardiac autonomic function. Assessment of heart rate variability may prove important role in
the risk stratification in such patients.
