[Typologic characteristics of central hemodynamics in the monkey in reclining and upright positions].
By tetrapolar rheography central hemodynamics was investigated in 74 rhesus monkeys in the reclining and orthostatic position. The basic hemodynamic parameters were examined in relation to the entire sample, to the groups with a higher or lower blood pressure (BPmean), and to four states of central circulation in orthostatic animals. The typological circulatory differences in the orthostatic state were shown to be determined by qualitatively different hemodynamic mechanisms responsible for BPmean. The hemodynamic characteristics in the reclining and orthostatic position were found to be reciprocally related. It is recommended to take into consideration the typological differences of hemodynamics that can modify cardiovascular responses to various effects.
