| 内容記述 | EKG and heart rate engaging in mountaineering as well as at rest were re- corded by the telemetry on three subjects of the 1965-1966 Nagoya university scientific and mountaineering expedition to the Andes at altitudes of 4200 to 7000 m (near the summit of Mt. Aconcagua, Argentina). Resting heart rate, 51-61 beats/min at sea level rose to 99-108 beats/min by a quick transition to an altitude (4200 m above sea level), but it became increasingly less during the course of high altitude acclimatization and reached 70-84 beats/min. Daily variation of the resting heart rate, within 12-14 beats/min at sea level, rose to 25-35 beats/ min at an altitude of 5000 m. Heart rate reached 130 beats/ min in subject N., 136 beats/min in subject I. and 163 beats/min in subject O. during engaging in mountaineering at the altitude of 4200-5000 m. The ceiling level of the heart rate seems to be 145 beats/min for the three sujects, and 163 beats/min of subject O. which is 20-25 beats/min above the ceiling level will be explained by another unknown mechanism. Heart rate of subject I. did not exceed 145 beats/ min even in mountaineering at an altitude of 7000 m. Heart rate fell markedly during sleep at 6200 m in all subjects. In subject O., it decreased to the resting heart rate at sea level and with such a marked fall in hesrt rate the subject could not perform strenuous mountaineering next day. Resting EKG of the subject was normal at 4200 m after altitude acclimatization, and as far as the heart r ate was within the ceiling level, there was observed no abnormal events in EKG. With increased heart rate to above 140 beats/min, depression of ST segment, ectopic beats and marked arrhythmia were observed in subject O. | |||||
