The modeling of the temperature changes and distribution in the myocardium

Abstract

This paper investigates the opportunities of applying the methods of noninvasive contactless diagnostics and numerical modeling for assessing the temperature gradient on the surface of the myocardium. These changes are observed on the surface of myocardium during hypo and hyperthermal processes, precisely during cardiopulmonary bypass (CPB). The 3D model of heat exchange in the myocardium is developed in the system MSC Sinda. Results of the performed measurements in the heart show that a noninvasive monitoring of the heart temperature using a thermographic camera in (CPB) conditions enables reliable measuring of the temperature of the myocardium during hypo and hyperthermal processes.
