在大量实验室工作及临床研究的基础上,论述了病毒性心肌炎与克山病诊断和鉴别诊断的条件,重点讨论了血清酶学和超声心动图在二者诊断和鉴别诊断上的价值,认为二者不仅临床表现、X线、心电图不同,血清酶学和超声心动图检查亦有显著不同,病毒性心肌炎和克山病是病因不同的两种疾病。 On the basis of a large number of laboratory work and clinical studies, the conditions of diagnosis and differential diagnosis of viral myocarditis and Keshan disease are discussed, and the value of serum enzyme and echocardiography in the diagnosis and differential diagnosis between the two is discussed The two not only clinical manifestations, X-ray, different ECG, serum enzyme and echocardiography also significantly different, viral myocarditis and Keshan disease are two different causes of the disease.
