Speckle tracking echocardiography (STE) is an emerging tool to characterize and quantify myocardial segmental and rotational mechanics. This literature review is aimed at clinical and academic cardiologists to provide: (1) a conceptual framework of STE to initiate understanding of myocardial mechanics; (2) evidence that three-dimensional (3D) STE overcomes the problems of time-consuming data acquisition and postprocessing seen with two-dimensional STE; and (3) illustrative clinical cases with analysis of myocardial mechanics via 3D STE to show the incremental value of strain in clinical decision making.
斑点追踪超声心动图（STE）是一种用于描述和量化心肌节段及旋转力学的新兴工具。这篇文献综述旨在为临床心脏病专家和学术心脏病专家提供：（1）STE的概念框架，以开启对心肌力学的理解；（2）证据表明三维（3D）STE克服了二维STE中耗时的数据采集和后处理问题；（3）通过3D STE分析心肌力学的示例性临床病例，以展示应变在临床决策中的增量价值。
