本实验目的为研究不同时间慢性间断减压缺氧时,大白鼠左、右心肌收缩和舒张性能受损的时间关系以及慢性缺氧大鼠肺动脉高压的发展与左、右心功能改变的关系。 实验用成年雄性大白鼠,共分四组:平原对照组(n=13),在模拟5000米高度的低压舱内(每天6小时)进行慢性间断缺氧
The objective of this study was to investigate the relationship between left and right cardiac contractile and diastolic dysfunction in chronic hypobaric hypoxia and chronic hypoxic hypoxia and the relationship between the development of pulmonary hypertension and left and right cardiac function in chronic hypoxic rats. Adult male rats were divided into four groups: control group (n = 13), chronic hypoxic hypoxia model (5000 hours)
