本文对196例各期矽肺患者和对照组104名健康工人进行了心电图描记测量与分析,两组工人的性别、年龄构成基本一致。检查结果,矽肺组的心电位顺钟向转位发生率11.2％明显高于对照组的发生率1.92％,两组有非常显著性差异(P<0.01)。矽肺组低电压发生率达6.1％,而低电压在正常人组中仅有1％发生率,经比较,有非常显著性差异(P<0.01)。并且是随着病期 In this paper, 196 cases of silicosis patients and control group of 104 healthy workers were measured and analyzed by electrocardiogram, the two groups of workers were basically the same gender and age. The examination results showed that the incidence of clockwise transposition of heart potential in silicosis group was significantly higher than that of control group (11.2%, 11.2%). There was a significant difference between the two groups (P <0.01). The incidence of low voltage in the silicosis group was 6.1%, while the low voltage in the normal group was only 1%. There was a significant difference (P <0.01) between the two groups. And with the disease
