In May 1975, one female mountaineer and eight male mountaineers of our country once more climbed onto the highest peak of the world Mount Qomolangma from the north slope. At the same time, we recorded 15 electrocardiograms while they were climbing from 7,600 m to the peak(8,848.13m) through radio-operated electrocardiography. In this report we mainly analyze the characteristics of electrocardiogram of six mountaineers who ascended the peak at the stage from 50 m a. s. l. to over 8,200m a. s. l. The result proves that although obvious changes after reaching an altitude above 8,200 m from the plain region should be those of indexes of heart rates, the QRS axis, Q-TR, Q-T/T-Q, P wave and T wave, there is no T wave diphasic, inverted, flat or abnormal shifting of S-T segment in the electrocardiogram of these outstanding mountaineers. This fully proves that those summit climbers are of excellent constitution and good adaptation ability to hypoxia. This also shows that the people who have been trained and acclimatized under hypoxia conditions (including permanent altitude residents and native lowlanders) can maintain normal physiological functions under ultra-anoxia for quite a long time.
1975年5月，我国一名女登山运动员和八名男登山运动员再次从北坡登上世界最高峰珠穆朗玛峰。与此同时，我们通过无线电心电图记录了他们从海拔7600米攀登至顶峰（8848.13米）过程中的15份心电图。在本报告中，我们主要分析了六名登山运动员在海拔从50米上升至8200米以上阶段登顶时的心电图特征。结果证明，虽然从平原地区到达海拔8200米以上后明显的变化应该是心率、QRS轴、Q - TR、Q - T/T - Q、P波和T波等指标的变化，但这些优秀登山运动员的心电图中没有出现T波双向、倒置、平坦或ST段异常移位的情况。这充分证明这些登顶者体质优秀，对缺氧具有良好的适应能力。这也表明，在缺氧条件下经过训练和适应的人群（包括长期居住在高原的居民和低海拔地区的本地人）能够在极度缺氧的情况下相当长时间地维持正常生理功能。
