Recent developments in echocardiographic speckle tracking have enabled the quantification of myocardial deformation. In addition to technical barriers, recent research has identified differences in strain measurements between vendors, reflecting differences in myocardial tracking, and how speckle strain is calculated and displayed. In this context, a paper in this issue of the journal emphasizes similarity of global longitudinal (but not radial and circumferential strain) between two vendors. The implications of these findings for the clinical application of strain are discussed.
超声心动图斑点追踪技术的最新进展使得心肌形变的量化成为可能。除技术障碍外，近期研究还发现不同厂家之间应变测量存在差异，这反映出心肌追踪以及斑点应变计算和显示方式的不同。在此背景下，本期杂志上的一篇论文强调了两家厂家之间整体纵向应变（而非径向和圆周应变）的相似性。本文讨论了这些发现对应变临床应用的影响。
