The accurate determination of left ventricular function is important for judging the prognosis of patients and the development of clinical treatment programs.Echocardiography has the advantages of low cost,non-invasive and easy to operate and repeatable.It has become the first choice of clinical evaluation of cardiac function and synchronicity.With the rapid development of ultrasound technology,a variety of new technologies to evaluate left ventricular function are also changing rapidly,of which,speckle tracking technology is particularly prominent.This paper reviews the recent advances of new echocardiographic techniques in the evaluation of left ventricular systolic function and synchronization.%左心室功能的准确测定对评判患者预后及制订临床治疗方案有着重要意义.超声心动图因具有费用低廉、无创伤及操作简便、可重复等优势,目前已成为临床上评价心功能与同步性的首选.随着超声技术的飞速发展,各种评价左心室功能的新技术也日新月异,其中斑点追踪技术尤为突出.现将超声心动图新技术在左心室收缩功能及同步性评价中的应用进展作一综述.
