EFFECT OF AUTONOMIC REGULATION ON DIASTOLIC FUNCTION OF LEFT VENTRICULAR ON THE BASE OF THE HEART RATE VARIABILITY INDEXES AT REST AND DURING TILT-TEST IN HYPERTENSIVE PATIENTS

The aim of the study was to evaluate correlation between diastolic function of left ventricular and autonomic regulation on the base of the heart rate variability indexes at rest and during tilt-test in hypertensive patients. 176 patients with hypertension were included in the study. The data obtained in this study shown that in hypertensive patients diastolic function of left ventricular correlate with autonomic regulation. The decrease of diastolic function associated with low indexes of heart rate variability and unfavorable prognosis concerning mortality in patients with hypertension. During tilt-test compensatory reserve of humoral, sympathetic and parasympathetic brunches was observed in hypertensive patients this decrease of diastolic function.
