用无创伤的方法诊断冠心病(CAD)是临床心血管病工作者面临的重大课题之一,各种负荷试验最常用的方法,传统的心电图运动试验敏感性和特异性均不理想,而且不能反应病变部位,动物试验和临床资料均已表明,心肌缺血时收缩异常的发生早于心电图异常。二维超声心动图(TDE)具有无创伤、易定位、易重复、探测范围大以及能够展现心内结构的空间方位关系等优点,具有更高的敏感性和特异性,
Diagnosis of coronary heart disease (CAD) by noninvasive methods is one of the major issues faced by clinical cardiovascular disease practitioners. The most commonly used methods of various stress tests are not ideal and traditional ECG test sensitivity and specificity, and can not Reaction lesions, animal experiments and clinical data have shown that myocardial ischemia, abnormal contraction occurs earlier than ECG abnormalities. Two-dimensional echocardiography (TDE) has the advantages of non-invasive, easy to locate, easy to repeat, large detection range and can display the spatial orientation of intracardiac structure, etc., with higher sensitivity and specificity,
