鉴于目前国内外文献中对高原铁路职工的心电图分析资料较少,本文分析了西宁地区铁路职工心电图异常检出率,并与南京地区比较,进而探讨高原低氧环境对心脏电活动的影响。对象与方法: 检查对象(见表1),分为高原组与平原组,分别为西宁、南京地区常居的铁路职工,无心脏病症状。采用日本光电7503型三道自动分析心电图机。于静息状态下,仰卧位描记常规十 In view of the lack of information on electrocardiogram analysis of railway workers in the plateau at home and abroad, this paper analyzes the anomaly detection rate of railway workers in Xining area and compared with Nanjing area, and then discusses the influence of plateau hypoxic environment on cardiac electrical activity. Subjects and Methods: The subjects (Table 1) were divided into plateau group and plain group, which were railway workers who lived in Xining and Nanjing respectively without heart disease symptoms. The use of Japanese photoelectric 7503 three automatic analysis of ECG. In resting state, supine position tracing routine ten
