摘要目的 了解高原驻守官兵心律失常的发生情况.方法 对2090例高原驻守官兵作常规心电图检查.按心律失常发作的类型、驻守时间和驻守海拔高度进行统计分析.结果 在2090例被检者中,心律失常发生率为19.81%,其中窦性心律不齐、窦性心动过缓、各种期前收缩占80.67%.海拔3000～3500 m组心律失常发生率与海拔>4000 m组心律失常发生率差异有统计学意义,分别为15.00%、26.82%(P<0.01);驻训3～6个月组和>1年组心律失常发生率差异无统计学意义,分别为20.49%、17.61%(P>0.05).结论 高原驻守官兵心律失常的发生率较高,心电图表现多种多样,高原心律失常的发生原因与缺氧程度有关,而与缺氧的持续时间无明显关系.

abstractsObjective To elucidate incidence of cardiac arrhythmia of officers and soldiers in Can Zi state. Methods A total of 2090 officers and soldiers were investigated. Electrocardiogram was analyzed by category of cardiac arrhythmia and was correlated with resided duration and altitude of stationed. Results The average incidence rate of cardiac arrhythmia was 19. 81% (414/2090). Sinus irregularity,sinus bradycardia and all kinds of premature systole were about 80. 67% (334/414) of all kind cardiac arrhythmia,48. 55% (201/414) ,18. 36% (76/414) ,13. 77% (57/414) respectively. There were significant differences between altitude of 3000 ～3500 m group and >4000 m group[ 15. 00% (186/1240) vs. 26. 82% (228/850) ,P<0. 01 ]. No significant difference was found between 3 ～ 6 months duration group and more than 1 year duration group (20.49% (327/1596) vs. 17. 61% (87/494) ,P>0. 05]. Conclusion Officers and soldiers in highland have the high incidence and variety of arrhythmia which is closely related with the level of hypoxia,and have nothing to do with the persistence time of hypoxia.
