1976年～1978年我们在青海高原用多种无创性方法观察了高原低氧环境对人体大小循环血流动力学和心脏功能的影响。本实验则进一步用直接法测定大鼠右心室收缩压,分析慢性低压缺氧条件下右心室收缩压升高和红血球增多与右心室肥厚的关系,探讨慢性低压缺氧下颈动脉体增生及共组织形态改变在右心室肥厚与右心室高压中的作用。
From 1976 to 1978, we used a variety of noninvasive methods on the Qinghai Plateau to observe the effect of plateau hypoxic environment on circulatory hemodynamics and heart function. In this study, the systolic pressure of right ventricle was further measured by direct method. The relationship between right ventricular systolic pressure and erythrocyte increase and right ventricular hypertrophy under chronic hypobaric hypoxia was analyzed, and the relationship between carotid body hyperplasia Role of tissue morphological changes in right ventricular hypertrophy and right ventricular hypertrophy.
