Abstract

An expression for the energy of motion of the wall of the left ventricle is developed. A cylinderical model is assumed for the left ventricle, and symmetry is used to produce the problem to a two-dimensional problem. Result obtained indicate that consideration of the energy of motion can be useful in problems of clinical diagnosis. Some correlation between previously published experimental results is also made with the equations derived in this paper.

摘要

推导了左心室壁运动能量的表达式。假设左心室为圆柱形模型,并利用对称性将问题简化为二维问题。所得结果表明,考虑运动能量在临床诊断问题中可能有用。本文还将先前发表的实验结果与推导的方程进行了一些关联。
