[Interrelationship between autonomic regulation and systolic function of left ventricular in patient with hypertension (based on heart rythm variability)].
A total of 176 patients with hypertensive disease (HD) were examined. The obtained data show that there is a relationship of the systolic function to autonomic regulation in HD patients. Those patients having displayed a decline in the systolic function had lower indices for the heart's rhythm variability, which fact suggested an unfavorable prognosis, with the decline in the activity of autonomous nervous regulation referrable to a greater extent to nervus sympathicus. Reaction to the tilt-test revealed compensatory reserves of the humoral link of regulation and sympathetic portion of the autonomic nervous system in patients presenting with a decline in the systolic function.
