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。
Objective: To compare the relationship between diagnosis of chronic high altitude sickness (CMS) and electrocardiogram. Methods: Based on the international CMS diagnostic scoring system, the survey of 95 young people in Karakorum at an altitude of 4 240m 5,001m and 5 300m in one year was conducted. The changes of CMS score, Hb, SaO2 and electrocardiogram were analyzed. Results: The scores of CMS and Hb in the abnormal ECG group were higher than those in the normal ECG group (P <0.05). There was no significant difference between the 5 001m group and the 5 300m group in the diagnosis of CMS (P> 0.05), but higher than the 4 240m group (P <0.01). Hb increased and SaO2 decreased at 5 001 m and 5 300 m groups compared with 4 240 m groups (P <0.01), but Hb at 5 300 m elevation was higher than that at 5 001 m group (P <0.05). The incidence of abnormal ECG at 5 001m elevation was higher than that at 4 240m (P <0.05), and the incidence of right ventricular hypertrophy at 5 001m elevation and 5 300m elevation was higher than 4 240m (P <0.01) And P <0.05). Conclusion: The level of CMS diagnostic scoring is consistent with the change of electrocardiogram.
