[The regional hemodynamic characteristics of subjects with different types of blood circulation].
The group of 56 young healthy men was divided into three subgroups according to the cardiac output values: hypo-, eu- and hyperkinetic types of circulation. Regional hemodynamics was studied in the head, lungs and shin by means of rheoplethysmographic technique. It has been shown that pulse blood filling of the vessels of all the regions studied significantly depends on the type of circulation. In persons with hyperkinetic type of circulation the pulse blood filling was more expressed than in those with hypokinetic type. The analysis of the tone of large and middle vessels of the lungs and shin has demonstrated opposite relations. The tone of head vessels reveals no correlation with the types of circulation. This fact may be explained by existence of pronounced autoregulation of the brain circulation.
