title: [Changes of cardiac kinetics during various stages of space flight].
abstract: Arterial blood pressure is dependent on ordinary cardiac function in human beings. Cardiac kinetics serves as important cardiovascular parameters during various stages of space activities. Although the reports about cardiac kinetics were not always in consistency during spaceflight, obvious changes during orthostatic stress after spaceflight were commonly observed. The mechanisms of orthostatic intolerance after spaceflight remain to be clarified, and the effects of changes of cardiac kinetics remain to be discussed. This paper briefly reviews the reports on cardiac kinetics during various stages of space activities and the researches on the mechanism of orthostatic intolerance after spaceflight.
