目的：掌握大批官兵急进高原的心电图变化；方法：仪器采用上海产ＥＣＧ－１１Ａ型，定准电压为１ｍ ｖ，走纸速度为２５ｍ ｍ ／秒，分别对１ ５００ｍ 、２ ８５０ｍ 、３ ８００ｍ 、５ ０３０ｍ 心电图各波、段值进行观察；结果：用自身对照ｔ检验统计学处理，心率随海拔增高而增加，节律随海拔增高而发生不齐的人数增加，Ｐ波随海拔增高而时间、电压增高，Ｐ－Ｒ间期和Ｑ－Ｔ间期无明显变化规律，Ｒ波在Ｉ、ａｖＦ、Ｖ５ 随海拔增高，振幅有逐步下降的趋势；Ｓ波在Ⅰ、Ⅲ、Ⅵ随海拔增高，振幅有逐步增高的趋势；Ｓ－Ｔ段改变随海拔增高而发生改变的例数增加；结论：我们认为心电图改变，可以做为军民在未来高原地区作战、施工、急进高原提供筛选人员的参考依据。
Objective: To master the electrocardiogram changes of a large number of officers and soldiers in the acute plateau. Methods: The instrument used the ECG-11A type manufactured in Shanghai with the standard voltage of 1mv and the paper feeding speed of 25m m / s, respectively, to 1 500m, 2 850m, 3 800m, Results: Compared with t-test, the heart rate increased with altitude, rhythm increased with altitude, the number of people with irregularity increased, P-wave increased with time, voltage increased, There was no obvious change rule between P-R interval and Q-T interval. The amplitude of R wave in I, avF and V5 increased gradually with the altitude increasing. The amplitude of S wave in Ⅰ, Ⅲ and Ⅵ increased with altitude, Increasing trend; S-T segment changes with increasing altitude increased the number of cases; Conclusion: We believe that changes in ECG, can be used as a military and civilian in the future plateau operations, construction, rapid advance plateau to provide screening staff reference.
