(一)本文用超声心动图、心电向量图、心电图及X线四项检查,按全国肺心病诊断标淮,对体检拟诊矽肺肺心病和矽肺肺气肿各60例进行验证,并以体检正常的40例作对照。结果四项的诊断特异性均尚好,向量图正确性较好,心动图敏感性较高,但两者与心电图互比无显著差异,X线敏感性正确性都最差,与前三者比较差异非常显著。四项联合检查特别前三项确能发现体检未能检出的早期肺心病病员,为矽肺肺心病早期诊断提供有效手段。(二)应用“基层诊断参考条件”诊断矽肺肺心病,早期病员漏诊者约占60％,强调观察舌腹面外周色泽变化,如呈淡紫、紫红或暗紫色即有诊断价值,可作为“基层诊断参考条件”发绀项的一点补充。(三)为区别矽肺肺心病不同于慢支肺心病,提出矽肺肺心病几点临床特征,并作简要讨论。
(A) The echocardiography, ECG vector chart, ECG and X-ray four check, according to the national diagnostic criteria for pulmonary heart disease, physical examination of silicosis and pulmonary heart disease emphysema 60 cases were verified and 40 cases of normal physical examination as a control. The results of the four diagnostic specificity are good, vector diagram correctness is good, high sensitivity cardiogram, but there is no significant difference between the two and ECG, X-ray sensitivity of the correctness of the worst, compared with the first three The difference is very significant. The first three of the four joint examinations can indeed detect the early pulmonary heart disease patients failed to detect the physical examination, and provide an effective means for the early diagnosis of silicosis pulmonary heart disease. (B) the application of “basic diagnostic reference conditions,” diagnosis of silicosis, early patient misdiagnosis accounted for about 60%, emphasizing the observation of the tongue ventral color change, such as was purple, purple or dark purple that has diagnostic value, can be used as “primary diagnosis Reference conditions ”cyanosis a little supplement. (C) in order to distinguish between silicosis and pulmonary heart disease is different from chronic pulmonary heart disease, proposed some clinical features of silicosis, and make a brief discussion.
