The heart is the hub of the circulatory system, a system of blood veins that distributes blood throughout the body. When arterial blood flow to a tissue, organ, or extremity is interrupted, it is known as ischemia. If left untreated, ischemia can cause tissue death. Since the heart's structure may be represented and simulated for cardiac contraction and relaxation, it is significant in COMSOL Multiphysics. The Fitzhugh-Nagumo (FN) and Ginzburg-Landau (GL) equations are used to implement the electrical activity in presumably different cardiac cavities with the ultimate goal of addressing ischemia-related problems. The heart model is divided into four distinct models to illustrate blood flow. Both the observed plots and the dependent variables' waves have a spiral shape.
