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准,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。结果四项诊断的特异性均尚好,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病员,为矽肺肺心病早期诊断提供有效手段。
In this paper, echocardiography, ECG vector chart, electrocardiogram and x-ray four check, according to the national diagnostic criteria for pulmonary heart disease, physical examination to be diagnosed in patients with silicosis and pulmonary heart disease 60 cases of pulmonary emphysema to verify, and physical examination of the normal 40 Example as a control. The results of the four diagnostic specificity are still good, the vector diagram is correct, high sensitivity cardiogram, but the two compared with the ECG was no significant difference. The correctness of x-ray sensitivity is the worst, compared with the first three differences is very significant. The first three of the four joint examinations can indeed detect early patients who fail to be detected in the physical examinations, and provide an effective means for the early diagnosis of silicosis pulmonary heart disease.
