摘　　要：超声心动图是最常见的评估心脏功能的方法,但这种技术有一定的局限性。超声斑点追踪技术利用高分辨率的二维灰阶图像分析声学斑点的运动轨迹,该技术时间分辨率较高,同时它又是由非多普勒技术发展而来,不受心脏整体运动和角度的影响,从而较组织多普勒成像能更真实、准确地反映心脏运动情况,为评价心脏心肌的扭转和变形提供一种全新的量化手段。Echocardiography is the most common cardiac function evaluation method,but with some limitations.Speckle tracking echocardiography（STE）,using two-dimensional gray-scale image to analyze acoustic spots motion trail,has a higher time resolution,unaffected by the whole heart movement and angle since it′s developed from non-Doppler technology,thus it can reflect the heart movement more realistically and accurately.STE provides a new method to quantitate myocardial torsion and deformation of heart.
