目的阐明电磁波同时混合存在于一个环境内是否会对青少年的心电活动和外周血细胞产生影响。方法采用心电图仪和全自动血球计数仪对106例青少年心电图和血常规进行检查。结果高背景环境电磁辐射组心率、PR间期、QRS波时间、QT间期、外周血血红蛋白含量和血小板数量与低背景环境电磁辐射组相比差异均无显著性,外周血白细胞总数明显低于低背景环境电磁辐射组(P<005)。从外周血白细胞分类来看,高背景环境电磁辐射组外周血单核细胞数量和男外周血嗜酸性粒细胞数量明显高于低背景环境电磁辐射组(P<005)。结论大都市现有环境电磁辐射对青少年(14～18岁)心电活动无明显影响,对外周血白细胞可能有一定的影响,主要表现在外周血白细胞总数下降,单核细胞和嗜酸性粒细胞数量相对增多,值得进一步研究。
Objective To elucidate whether the simultaneous presence of electromagnetic waves in an environment can have an impact on the cardiac electrical activity and peripheral blood cells of adolescents. Methods 106 cases of adolescent electrocardiogram and blood routine were examined by electrocardiograph and automatic blood cell counting. Results There was no significant difference in heart rate, PR interval, QRS time, QT interval, hemoglobin content and platelet count between high background electromagnetic radiation group and low background electromagnetic radiation group. The total number of peripheral white blood cells was significantly lower Low background ambient electromagnetic radiation group (P <005). From the classification of peripheral blood leukocytes, the number of peripheral blood mononuclear cells and the number of male peripheral blood eosinophils in the high background electromagnetic radiation group were significantly higher than those in the low background electromagnetic radiation group (P <005). Conclusion The current environment of the metropolitan electromagnetic radiation on the adolescents (14-18 years of age) had no significant effect on ECG, peripheral blood leucocytes may have some impact, mainly in the total number of peripheral white blood cells decreased monocytes and eosinophils The relative increase in quantity deserves further study.
