我们曾在“缺氧性肺动脉高压的发展与心输出量动态变化的关系”中报道:大鼠在模拟5,000m高度的低压舱内连续减压缺氧4、10、20天,其右心室收缩压RVP(相当于肺动脉收缩压)、右室±(dp/dt)max(反映心肌舒缩功能)、心输出量CO,每搏量SV和心指数CI均随缺氧时间的延长而逐步升高,左室压LVP与左室±(dp/dt)max则无明显改变。本文延 We have in the “relationship between the development of hypoxic pulmonary hypertension and cardiac output dynamic changes” reported: rats in a simulated low-pressure cabin at a height of 5,000m hypoxia continuously hypoxia 4,10,20 days, the right ventricular contraction RVP (equivalent to pulmonary systolic pressure), right ventricular ± (dp / dt) max (reflecting myocardial systolic and diastolic function), cardiac output CO, stroke volume SV and cardiac index CI gradually increased with hypoxia time There was no significant difference in LVP and ± ± (dp / dt) max in left ventricular pressure.
