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.
