The analysis of heart rate variability (HRV) in the supine position (initial state) and during orthostasis in patients with arterial hypertension (AH) of 1 and 2 degrees of both sexes aged 45-60 years was carried out. In men with AH 1 degree during orthostasis, the heart rate increases from 73 to 91 beats/min (p<0.01), SI - from 164 to 241 rel. units. In men with AH 2 degree, the heart rate during orthostasis increases from 78 to 97 beats/min., SI - from 239 to 354 rel. units. In women with AH 1 and 2 degrees during orthostasis, the heart rate rises from 76-80 to 95-98 beats/min, SI - from 196-278 to 357-407 rel. units, the variability indicators remain higher in patients with AH 1 degree. The results indicate that patients with AH 2 degree show signs of increased activity of sympathoadrenal regulation mechanisms, and the vasomotor center is more activated during orthostasis. Patients with AH 1 degree are characterized by a greater contribution of the autonomous circuit and the parasympathetic channel to the regulation of heart rhythm with less activity of the sympathoadrenal system and the vasomotor center. Consequently, the body of patients with AH 1 degree has higher functional capabilities of the heart rhythm regulation system to adapt to various loads.
Keywords:arterial hypertension, heart rate variability, orthostatic test, autonomic reactivity, functional reserves
