[Comprehensive study of central and regional hemodynamics in hypertension using bloodless research methods]

Tetrapolar chest rheography is a convenient, noninvasive method for determining the stroke and minute blood volumes. Its application made it possible to reveal various types of hemodynamics in patients with hypertensive disease and apply differentiated treatment with due account for these peculiarities. Study of regional hemodynamics showed a significant increase in the tonus of the arteries of the brain and crura and diminished tonus of the veins. The method is most valuable in a follow-up during treatment and particularly for recording rapid shifts in hemodynamics in functional loads. Assessment of the reactions of patients with hypertensive disease during the orthostatic test revealed various degrees of disorders of the circulatory system adaptation mechanisms; with the progression of the disease these disorders become more intense.
