Abstract
The instantaneous local temperature distribution across the wall of the left ventricle (LV) in the heart is obtained by solving the bio-heat energy balance equation, utilizing the distributed oxygen demand, and the time dependent local coronary perfusion, coupled with our spatial and temporal mechanical model of the L. V. 1-D model approximations of the cycle-averaged and time dependent local temperatures are presented for the normal 'symmetric' heart. And a 2-D model yields the time averaged local temperatures for an infarcted non-symmetric LV. Effects of heart rate, blood perfusion rate and the external wall free convection boundary condition are investigated. The calculated 1-D results are found to be in fair agreement with experimental data. The 2-D temperature distributions indicate that the infarcted region has a very pronounced local effect, which decreases rapidly out of the region in the circumferential direction. The results suggest the thermal procedure as a potential aid for the identification of infarcted regions in the muscle of the heart.
