This report deals with the differences and changes of physiological functions of the highlanders and the lowlanders at different altitudes during the period when the Chinese Mountaineering Team was climbing up and reached the peak of Qomolangma Feng. In a period of relaxation, there are no significant changes in ventilatory responsiveness to hypercapnia, electrocardiogram and electroencephalogram between highlanders and lowlanders with the changes at different altitudes. At 5,000 m a.s.l., however, electrocardiogram and the result of cardiac ventricular functional test show significant differences after the subjects are physically loaded. Those whose electrocardiogram readings show unusual changes, and whose cardiac ventricular functional tests show their physiological functions at low degree after physical activities at the altitude of 5,000 m, have a climbing ability hardly below 6,500 m, while those who have reached the altitudes above 8,200 m have no unusual changes in electrocardiogram, and the results of cardiac ventricular functional tests show that their physiological functions are at high degree.
本报告探讨了中国登山队攀登并到达珠穆朗玛峰顶峰期间，不同海拔高度的高原人和低地人的生理功能差异及变化。在一段放松期内，高原人和低地人对高碳酸血症的通气反应性、心电图和脑电图在不同海拔变化时均无显著差异。然而，在海拔5000米处，受试者进行体力负荷后，心电图和心室功能测试结果显示出显著差异。在海拔5000米处进行体力活动后，心电图读数显示异常变化且心室功能测试表明其生理功能处于低水平的人，其登山能力几乎无法低于6500米，而那些到达海拔8200米以上的人，心电图无异常变化，心室功能测试结果表明其生理功能处于高水平。
