喀喇昆仑山不同海拔高度驻防一年的青年慢性高原病诊断计分与心电图对比分析

目的:对比分析慢性高原病(CMS)诊断计分与心电图之间的关系。方法:依据国际CMS诊断计分系统对喀喇昆仑山海拔4 240m5、001m和5 300m驻防一年共95名青年的调查,并将CMS诊断计分、Hb、SaO2与心电图改变对比分析。结果:异常心电图组CMS诊断计分和Hb均较正常心电图组增高,差别有显著性(P<0.05)。海拔5 001m组与5 300m组CMS诊断计分比较差别无显著性(P>0.05),但均高于4 240m组(P<0.01)。海拔5 001m组和5 300m组与4 240m组比较,Hb增高,SaO2降低,差别有非常显著性(P<0.01),而海拔5 300m组Hb又高于5 001m组,差别有显著性(P<0.05)。海拔5 001m组异常心电图的发生率较4 240m组增高(P<0.05),海拔5 001m组和5 300m组右心室肥厚的发生率均较4 240m组增高,差别有显著性意义(P<0.01和P<0.05)。结论:CMS诊断计分的高低与心电图的变化相一致。

Correlation between Chronic Mountain Sickness Diagnosis Points and Cardiogram in Youths Stationed at Different Altitudes on KalaKunlun Mountain

Objective: To comparative analyze the correlation between chronic mountain sickness(CMS)diagnosis points and cardiogram at high muontain.Methods: 95 youths stationed at altitude of 4 240m,5 001m and 5 300m for one year were investigated by international CMS diagnosis grade system and the level of Hb,SaO2 and cardiogram were examined and the results were compared with the CMS points.Results:The CMS diagnosis grade and Hb in exceptional cardiogram group were higher than those in normal cardiogram group(P<0.05).There was no significant difference between group 5 001m and group 5 300m with CMS diagnosis point(P>0.05) but they were higher than group 4 240m(P<0.01).The level of Hb and SaO2 in group 5 001m and group 5 300m were significantly higher than group 4 240m(P<0.01)and Hb in group 5 300m was also higher than group 5 001m(P<0.05).Exceptional Cardiogram incidence in group 5 001m was higher than group 4 240m(P<0.05).Right ventricle hypertrophy in 5 001m and group 5 300m were more than group 4 240m(P<0.01,or P<0.05).Conclusions: CMS diagnosis points and ECG changes were consistent with the level.
