【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。
[Abstract]:The maintenance of human normal arterial blood pressure depends on the normal cardiac function. The cardiac dynamic parameters are one of the key points in various stages of manned spaceflight activities abroad. Although the reports on cardiac dynamic parameters in spaceflight are not consistent, However, it was generally observed that cardiac dynamic parameters changed greatly during postspace orthostatic stress, and the mechanism of decreased orthostatic endurance was not clear. The effects of cardiac dynamics on endurance in different positions need to be discussed. The changes and mechanism of cardiac dynamics in various stages of manned spaceflight activities abroad are briefly summarized in this paper.
