摘要:
作者通过对00例移居高原地区(海拔2780 m和2900 m的格尔木、柯柯地区)5～1O年的健康男性铁路职工在当地进行无创性心功能检测，结果显示：心排指数，每搏指数，心肌收缩指数，心肌收缩变力指数，射血分数，胸腔液体指数及心率，与世居南京居民无显著差异(P>0.05)；而心脏前负荷，系统血管阻力指数，左心作功指数，平均动脉压有显著差异(P<0.05)。从而进一步揭示机体进入高原低氧环境后，在代偿性机制建立的“习服"过程中，心血管系统发生的变化。
Abstract:
This article analyses the results of non-invasive cardiac function tests on 100 healthy railroad workers who have worked in places of high altitudes(Germu and Keke，2870 m and 2900 m above sea level，respectively)for about a decade of years．The results indicate that there is no obvious change in cardiac output index，stroke output index，myocardial contraction index，myocardiac contraction inotropie index，ejection fraction index and heart rate,P>0.05．However there are significant differences in cardiac preload，cardiac postload，left cardiac work index and mean arterial pressure，P<0.05．These are the changes of cardiovascular system taking place in hypoxia environment in the places of high altitudes and during the habituation founded by the compensatory mechanism．
