[Hemodynamic shifts as affected by the physical loading of persons with different blood pressure levels in relation to the blood circulatory type].

Tetrapolar chest rheography was used to study central hemodynamic shifts in response to submaximum physical stress in 29 normal subjects, 26 individuals with marginal hypertensive conditions and 28 patients with labile arterial hypertension. Physical stress tolerance and cardiovascular performance were shown to decline as arterial hypertension developed; differences between individual hemodynamic types, demonstrated at rest, persisted at the peak of exercise; hypokinetic circulation was associated with the poorest cardiovascular performance.
