应用ＡＴＬ－ｕｌｔｒａｍａｒｋ超６型彩色多普勒超声诊断仪诊断扩张型心肌病１００例，并与性别、年龄相应的正常人对比分析。结果：除扩张型心肌病各组室间隔及左室后壁舒张期厚度与相应正常对照组相比无显著性差异（Ｐ＞０．０５）外，其左室舒张内径及收缩内径、左房内径明显大于正常对照组（Ｐ＜０．０１），左室射血分数及左室内径缩短分数较正常对照组明显降低（Ｐ＜０．０１），并见心腔内血流速度缓慢，颜色变淡。另在７７例病人中探及４０例瓣膜返流。提示该诊断方法对扩张型心肌病具有直观、简便、准确、迅速的优点，为本病的诊断及鉴别诊断提供了良好的手段。
100 cases of dilated cardiomyopathy were diagnosed by ATL-ultramark ultrasonography 6 color Doppler ultrasonography, and compared with the gender and age-matched normal subjects. Results: In addition to the dilated cardiomyopathy group ventricular septal and left ventricular posterior wall diastolic thickness compared with the corresponding normal control group had no significant difference (P> 0.05), the left ventricular diastolic diameter and systolic diameter, left atrial The diameter of left ventricular ejection fraction and the shortening of left ventricular diameter were significantly lower than those of normal control group (P <0.01), and the intracardiac flow velocity was slow and the color Fades In another 77 cases of patients and exploration of 40 cases of valve regurgitation. Prompt diagnosis of dilated cardiomyopathy with intuitive, simple, accurate and rapid advantages for the diagnosis and differential diagnosis of the disease provides a good means.
