摘　　要：随着超声心动图定量分析技术的发展和应用,对收缩后收缩(PSS)和收缩早期伸长(ESL)这类微小心肌运动的分析得以实现。PSS和ESL可客观且早期地评估心功能受损情况,在诊断心肌缺血方面较常规参数更有优势,在非缺血性心脏疾病的心功能评估中也有一定的应用价值。本文就超声心动图定量分析PSS和ESL在心脏疾病中的研究进展进行综述。With the extensive application of quantitative analysis techniques of echocardiography,the analysis of subtle myocardial movements such as postsystolic shortening(PSS)and early systolic lengthening(ESL)has been realized.PSS and ESL can objectively and early assess the condition of impaired heart function.They have more advantages than conventional parameters in diagnosing myocardial ischemia.In addition,PSS and ESL are also useful parameters for the evaluation of cardiac function of non-ischemic heart diseases.This article reviews the research progress of echocardiographic quantitative analysis of PSS and ESL and their applications in heart diseases.
