Spatial and temporal temperature distribution in the healthy and locally diseased wall of the heart

Abstract The radial and circumferential temperatures in the wall of left ventricle (LV) of the heart are obtained by solving the bio-heat energy equation for cases of regional death of the muscular tissue (local infarction) or local deprivation of oxygen supply (hypoxia) to the muscle. The model is an extension of our one-dimensional solution for the radial instantaneous temperatures in the wall, based on our mechanical model of the LV function. A similar approach yields the effects of the nonsymmetric boundary conditions imposed by the right ventricle (RV) on the temperature distribution in the LV wall. The results indicate very pronounced local temperature gradients due to local myocardial dysfunctions or unsymmetric boundary conditions on the wall.
