A membrane theory model of the infarcted left ventricle is described which represents the pressure-volume relation of the ventricle in diastole and end-systole, states in which the contraction velocity is zero. This membrane theory model is shown to give essentially the same diastolic pressure-volume relation as a more elaborate model which fully accounts for variations through the wall thickness. The end-systolic pressure-volume relation of an infarcted ventricle is obtained by means of a specially tailored finite element method, which is described in detail. From the end-systolic and diastolic pressure-volume relations the effect of infarction on the pumping performance of the ventricle can be determined. Representative numerical results are presented. 1983.
