摘要
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。
One hundred patients with dilated cardiomyopathy were examined by ATL ultramark 6colour Doppler ultrasonic apparatus,and compared with 100 mormal subjects。The resultswere as follows:The left ventricular diastolic dimension(LVDd),the left ventricular sys-tolic dimension(LVDs)and the left atrium dimension(LAD)of the patients’group were ob-viously larger,while their EF and FS were lower than those of normal group(P<0.01 )。There was no significant difference in the intervcntricular septal thickness(IVST)and theleft ventricular diastolic wall thickness(LVPWT)between the patients’and normal groups(P>0.05).The velocitv of blood flow in both atria and ventricles decreased in thepatients,group.Valvular regurgitation was demons,trated in 40 of 77 patients。The resultssuggest that duplex Doppler echocardio-graphy is a simple,easy,rapid and reliable methodwhich offers an approach to the diagnosis and differential diagnosis of dilated car-diomyophathy.
