摘　　要：心肌应变率成像(SRI)是组织速度成像基础上发展起来的一种超声心动图技术,可作为评价心房局部心肌功能的量化指标,目前在各种心脏疾病中的应用得到广泛研究。本文阐述了SRI的定义、测量方法及优缺点,并对其在评价一些心脏疾病左房局部功能的应用进展做一综述。Myocardial strain rate imaging is a new technology developed from tissue Doppler imaging which can be used for a quantitative index to evaluate local myocardial function. The myocardial strain rate imaging have been studied widely in all kinds of heart diseases. This article reviews the definition,measurements,virtue and limitations of myocardial strain rate,and discusses its clinical application on evaluation of left atrial local function in patients with heart disease.
