【摘要】 本实验比较了具有三种不同心收缩功能潜力被试者在运动后心动时相的变化,找出了反映他们心收缩功能的三个时相参数(IC、LVET/R-R、MT/R-R),据此制定出航天员心脏收缩功能的选拔标准,对其实验依据及应用价值进行了讨论.更多还原

【Abstract】 Systolic time intervals(SIT) after 3 min. exercise were compared among three kinds of subjects with different cardiac contraction function.The results showed that the isovolumetric contraction period(IC), ejection index (LVET/R-R) and mechanical contraction index (MT/R-R) are useful indices for assessment of cardiac function. According to the three indices the selecting standard of astronauts was established and it’s experimental evidence and application were discussed更多还原
