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.
动脉血压取决于人类正常的心脏功能。心脏动力学是太空活动各个阶段重要的心血管参数。尽管关于太空飞行期间心脏动力学的报告并不总是一致，但太空飞行后立位应激时的明显变化是普遍观察到的。太空飞行后体位性不耐受的机制仍有待阐明，心脏动力学变化的影响也有待探讨。本文简要回顾了关于太空活动各个阶段心脏动力学的报告以及太空飞行后体位性不耐受机制的研究。
