Authors present a new study of left ventricular local wall motion. A critical study about three methods is analysed. This original analysis method is based on the calculation of local ejection fractions from a mathematical model: a theoretical ideal systolic contour is evaluated from an ejection fraction value and for a left homogeneous ventricular contraction. The left regional wall motion is appreciated from the comparison between real systolic contour and theoretical systolic contour. At first the use problems of classical regional wall motion study are described. This presentation is to develop the mechanical and mathematical particularities of our original method. On the other one the study of computer-derived shape is to allow systematical and quick application to quantify the left ventricle contractility.
作者介绍了一项关于左心室局部壁运动的新研究。分析了一项关于三种方法的批判性研究。这种原始分析方法基于从数学模型计算局部射血分数：根据射血分数值并针对左心室均匀收缩来评估理论理想收缩轮廓。通过实际收缩轮廓与理论收缩轮廓之间的比较来评估左心室局部壁运动。首先描述了经典局部壁运动研究的使用问题。本介绍旨在阐述我们原始方法的力学和数学特性。另一方面，对计算机生成形状的研究是为了实现系统且快速的应用，以量化左心室收缩力。
