对６０例以心脏明显扩大的病人进行心脏二维超声（２－ＤＥ）检查并与Ｘ线诊断对照分析。结果表明，二维超声对各类心脏疾病有较明显的特征性表现，对大心脏的诊断和鉴别诊断明显优于Ｘ线。此外还对扩张型心肌病、心包积液、冠心病等心脏疾患的二维超声诊断进行讨论。
Sixty patients with cardiac enlargement were examined by two-dimensional echocardiography (2-DE) and compared with X-ray diagnosis. The results show that two-dimensional ultrasound has obvious characteristic manifestations for all kinds of heart diseases. The diagnosis and differential diagnosis of the large heart are superior to X-ray. In addition, we also discuss the two-dimensional ultrasonic diagnosis of dilated cardiomyopathy, pericardial effusion and coronary heart disease.
