105例高原官兵心电图ST-T改变分析

Analysis of ST-T abnormality of 105 highland officers and soldiers

目的了解高原官兵心电图ST-T改变的发生情况及其意义。方法对2090例高原驻守官兵作常规心电图检查。对不同年龄、海拔及驻训时间进行比较。结果在2090例被检者中,ST-T改变发生率为5.02%(105/2090),各年龄组ST-T改变发生率差异无统计学意义,P>0.05。海拔3000～3500m组ST-T改变发生率与海拔>4000m组ST-T改变发生率差异有统计学意义,分别为3.55%(44/1240)、7.18%(61/850),P<0.01;驻训3～6个月组与>1年组ST-T改变发生率差异无统计学意义,分别为4.51%(72/1596)、6.68%(33/494),P>0.05。结论高原官兵ST-T改变发病率与年龄及驻训时间无关,与驻训海拔高度相关。对ST-T改变的诊断应持慎重态度,应结合临床综合判断。

Objective To elucidate Incidence and its clinical implication of ST-T abnormality of highland officers and soldiers in Gan Zi state.Methods A total of 2090 officers and soldiers were examined.The different age,altitude of stationed and time were compared.Results The average incidence rate of ST-T abnormality was 5.02%（105/2090）.No significant difference was found in different age groups of ST-T abnormality,P0.05.There were significant differences between altitude of 3000～3500 m group and 4000 m group which ST-T abnormality rate respectively were 3.55%（44/1240）,7.18%（61/850）,P0.01.No significant difference was found between 3～6 months group and more than 1 year group which ST-T abnormality rate respectively were 4.51%（72/1596）,6.68%（33/494）,P0.05.Conclusion The age and stationed time have little effect on ST-T abnormality rate of Highland officers and soldiers.Stationed altitude have a posive correlation with ST-T abnormality.The diagnosis of ST-T abnormality should be combined with clinical comprehensive judgement and treated cautiously.
