区域性室壁运动异常(RWMA)是诊断冠心病较特异的指标,局部心肌缺血是其发生原因。目前,两维超声心动图是观察RWMA的良好手段。目测分析法简便实用,但有主观性。实验研究中,多采用心腔轮廓分析法。近期发展的时空综合分析法精确、敏感。90％的急性心肌梗塞(AMI)节段有RWMA出现,但其程度与梗塞层厚度有关。
Regional wall motion abnormalities (RWMA) is a more specific diagnosis of coronary heart disease indicators, the local myocardial ischemia is the cause. At present, two-dimensional echocardiography is a good way to observe RWMA. Visual analysis is simple and practical, but subjective. Experimental study, the use of heart contour analysis. The recent development of integrated spatio-temporal analysis method is accurate and sensitive. RWMA occurs in 90% of acute myocardial infarction (AMI) segments, but its extent is related to infarct thickness.
