Abstract

The stress-strain relationships of heart muscle in the interventricular septum, anterior free wall, lateral free wall, and posterior free wall of a working canine left ventricle were determined during two slow-filling phases of diastole, four ejection phases of systole, and one fast relaxation phase of diastole of a cardiac cycle. A plane-strain finite-element model was employed for the quantitative analysis of the stress and strain changes during these seven phases based on the true shape and dimensions of the left ventricle reconstructed at eight instants of the cardiac cycle by application of cylindrical scanning computerized tomography.
