摘　　要：目的：探讨斑点追踪显像技术在心血管疾病超声检查中的应用.方法：在PubMed和中国期刊全文数据库中查阅近年来国内外的相关文献,并做进一步综合分析.结果：应用斑点追踪显像技术测定心肌运动的应变及应变率,能更准确的评价心肌整体与局部的功能.结论：斑点追踪显像技术检查无角度依赖性,其判断室壁运动的敏感性及准确性优于以往相关超声检查方法.Objective：To investigate the application of speckle tracking imaging in the diagnose of car- diovascular diseases. Methods：To look up the relevant Chinese and foreign literatures in PubMed and the CNKI in recent years, and make further comprehensive analysis. Results：The strain and strain rate of wall mo- tion, which have close relationship with allomeric function and regional function of ventricular wall, can be determined by speckle tracking echocardiography. Conclusions：There is no angular dependence speckle tracking echocardiography, and it is more sensitive and accurate than previous related ultrasound methods.
