title: [Changes in hemodynamics during increase of functional loading of the cardiovascular system].
abstract: It has been executed 26 experiments on dogs in order to investigate the changes of haemodynamics during narrowing of ascending aorta and brain ischaemia. It has been setted during investigation, that cardiovascular system possesses high compensatory abilities. This system fully restored the disorders in blood circulation during 3 minutes of occlusion of brachiocephalic trunk or during 5 minutes of narrowing. The restoration of normal blood circulation after 5 minutes leads to normalization of indicators of haemodynamics also in 5 minutes and does not lead to decompensation of cardiac function. The heart decreases the rate of contractions in order to support the high level of its force in such a conditions.
