摘　　要：无创心肌作功是最新发展的一项超声心动图技术。其结合二维斑点追踪与无创估测左室压力技术,得到左室从二尖瓣闭合到二尖瓣开放期间的心肌各节段及整体的作功,能够定量、客观且敏感地评估心肌局部及整体功能,对于各种心血管疾病的评估有一定优势,有良好的应用前景。Noninvasive myocardial work is a newly developed echocardiography technology.It combines two-dimensional speckle tracking imaging and noninvasive estimation of left ventricular pressure to obtain the work of each segment and the whole left ventricle from mitral valve closure to mitral valve opening.It can quantitatively,objectively,and sensitively evaluate the regional and global myocardial function,showing advantages in evaluating various cardiovascular diseases,and might have a great application prospect.

关 键 词：无创心肌作功 压力应变环 二维斑点追踪技术
