The aim of this paper is to emphasise the role of the primary strain-line patterns in a human left ventricle (LV) within the complex system that is the heart. In particular, a protocol is proposed for the measurement of the principal strain lines (PSL) in the walls of the LV; this protocol is tested by means of a computational model which resembles a human LV. When the analysis is focused on the epicardial surface, PSL can be used to derive information on the directions of muscle fibres during the entire cardiac cycle, not only the systolic phase.
本文的目的是强调在作为一个复杂系统的心脏中，人类左心室（LV）主要应变线模式的作用。特别是，提出了一种用于测量左心室壁上主应变线（PSL）的方案；该方案通过一个类似于人类左心室的计算模型进行测试。当分析集中在心外膜表面时，主应变线可用于获取整个心动周期（不仅是收缩期）中肌纤维方向的信息。
