肺心病是严重危害劳动人民健康的常见病、多见病,早期诊断和及时治疗是十分重要的。可是肺心病的早期诊断比较困难,因为肺心病多伴有肺气肿、心脏转位以及低电压,在心电图上反映受到影响;又由于解剖上左右心室原来在厚度上有差别,右心室则要求肥厚到相当程度才能在心电图上记录出来。因此,心电图在肺心病的诊断上,虽然是重要而常用的方法,但敏感性较低。根据国内外的研究,因采用的诊断标准有所不同,所得的阳性率亦有所差别,从33.3％到81％不等。1973年我国于全国肺心病专业会议上曾讨论提出了一个
Pulmonary heart disease is a common disease that seriously endangers the health of working people. It is very important to have early diagnosis and timely treatment of common diseases. However, the early diagnosis of pulmonary heart disease is more difficult because of multiple pulmonary heart disease accompanied by emphysema, cardiac transposition and low voltage, reflected in the ECG is affected; and because of the anatomy of the original left and right ventricular thickness in the original differences, the right ventricle is required To a considerable extent hypertrophy can be recorded on the ECG. Therefore, ECG in the diagnosis of pulmonary heart disease, though it is an important and commonly used method, but less sensitive. According to the research at home and abroad, due to the different diagnostic criteria adopted, the positive rates obtained also vary from 33.3% to 81%. In 1973, China had discussed and put forward one at a national pulmonary heart disease professional conference
