摘　　要：人体正常动脉血压的维持依赖于心功能正常。国外载人航天活动各阶段心脏动力学参数是检测的重点之一。虽然航天中有关心脏动力学参数的报道不尽一致 ,但一般都观察到航天后立位应激时心脏动力学参数有较大变化 ,立位耐力降低的机理尚不清楚 ,心脏动力学变化对立位耐力的影响也有待探讨。本文对国外载人航天活动各阶段有关心脏动力学的变化及变化机理作一简要概述。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.
