During a Karakorum expedition electrocardiographic investigations were performed. In the basic camp, 4,800 meters above sea level, ECG of test persons were registered in the resting state and after physical exercise. In addition, long-time recordings of heart rate reactions were made during various phases of mounting up to a height of about 7,800 meters. The ascent in extreme altitudes without an artificial oxygen supply did not cause electrocardiographical signs of myocardial hypoxia. Only supraventricular or ventricular ectopic beats could be detected in some instances. During continuous mounting, the heart rate rises to 120-140 beats per minute and reached 150 beats per minute during the last part up to the summit. Resting blood pressure measured in the basic camp over a period of 15 days showed no significant changes.
在一次喀喇昆仑探险期间进行了心电图检查。在海拔4800米的大本营，对测试人员在静息状态和体育锻炼后的心电图进行了记录。此外，在攀登至约7800米高度的各个阶段，还对心率反应进行了长时间记录。在没有人工供氧的情况下攀登至极高海拔并未引起心肌缺氧的心电图迹象。仅在某些情况下可检测到室上性或室性异位搏动。在持续攀登过程中，心率上升至每分钟120 - 140次，在最后登顶阶段达到每分钟150次。在大本营为期15天测量的静息血压未显示出显著变化。
