提出了一种基于力学的三维斑点跟踪超声心动图数据分析，旨在研究心肌变形，并评估与心脏组织主应变线对应的不同应变线的形状和功能。该分析是基于应用程序的测量方案的心内膜和心外膜的主应变线，这已经在模拟左心室进行了测试。与类似的研究相比，它建立了内膜主应变线不能识别任何结构纤维，甚至没有沿着收缩期，并建议这是由于内膜表面的能力，以对比左心室的扩张。(C)2014爱思唯尔有限公司版权所有。
A mechanics-based analysis of data from three-dimensional speckle tracking echocardiography is proposed, aimed at investigating deformations in myocardium and at assessing shape and function of distinct strain lines corresponding to the principal strain lines of the cardiac tissue. The analysis is based on the application of a protocol of measurement of the endocardial and epicardial principal strain lines, which was already tested on simulated left ventricles. In contrast with similar studies, it is established that endocardial principal strain lines cannot be identified with any structural fibers, not even along the systolic phase and is suggested that it is due to the capacity of the endocardial surface to contrast the dilation of the left ventricle.
