本文将76年确诊为矽肺患者285例,比较其76～80年四年共三次的心电图演变。随着矽肺病情恶化或出现并发症,心电图异常检出率相应增多。在出现77年全国肺心病会议修订的心电图诊断指标之前,其检出率高的,依次是:IPI—V_1逐渐增大,至≥0.03毫米秒;P波电轴逐次右偏直至>80°;QRS电轴逐渐右偏以及右胸导联T波改变等。所以我们认为早期肺心病的心电图诊断,应是动态随访观察,其观察项目可为:IPI—V_1、P电轴、电压、QRS电轴、右胸导联T波、Ⅱ、Ⅲ、a v F的ST段、不全或完全性右束支传导阻滞以及出现77年全国心电图诊断指标的其他条件。
In this paper, we diagnosed 285 patients with silicosis in 76 years and compared their electrocardiographic changes for three years from 76 to 80 years. With the deterioration of silicosis or complications, a corresponding increase in the detection rate of ECG abnormalities. In the 77-year national pulmonary heart disease conference before the revised ECG diagnostic indicators, the detection rate was high, followed by: IPI-V_1 gradually increased to ≥ 0.03 mm s; P-wave power axis right to right-sided to> 80 °; QRS axis gradually right and right chest lead T wave changes and so on. Therefore, we believe that the diagnosis of early pulmonary heart disease ECG should be dynamic follow-up observation of its observation items can be: IPI-V_1, P axis, voltage, QRS axis, right chest lead T wave, Ⅱ, Ⅲ, av F ST-segment, incomplete or complete right bundle branch block, and other 77-year national ECG diagnostic criteria.
