高原低氧环境下地质职工异常心电图分析

ANALYSES OF ABNORMAL ELECTROCARDIOGRAM TO GEOLOGICAL WORKERS WHO LIVED IN ENVIRONMENT OF LOW OXYGEN PLATEAU

对青海高原地质职工的236例异常心电图分析发现,异常心电改变比率较高。不同年龄组异常心电图表现以SV_5增深、心电轴左偏、ST-T 改变、不完全性右束支传导阻滞、左前半支传导阻滞、心电轴右偏及QRS低电压等改变率较高为特征。在高原缺氧环境下,人体氧自由基代谢失衡,易致机体组织、器官损害老化和心、脑、肺、肾脏器等的损害。文章指出,服用“复方红景天”胶囊等抗低氧药物有利于地质职工及高原居民的健康。

Based on the analyses of abnormal electrocardiogram to 236 medical recordsof geological workers who lived on Qinghai-Xizang platesu, the authors have found that theratio of abnormal electrocardiac is high. The abnormal electrocardiograms of various age-group are characterised by hyperplasia of SV_5. left-or-right deviation of electrocrdiac axis,change of ST-T conduction obstrucfion, and QRS low voltage, etc. In the environment ofoxygen lacking plateau, the loss of metabolism balance of oxygen free radical in human bodyis inevitably resulted in ageing and damaging of human body or organs, e. g. heart, brain,lungs, kidney .etc. It is advantageous to the health of geological workers and other plateauinhabitant to take such medicines of low oxygen resisting as Hongjingtian compound.
