This paper presents a computational framework for modeling electrical signal propagation in cardiac tissue using two complementary mathematical models implemented within a multiphysics simulation environment. The FitzHugh-Nagumo equations are employed to describe the excitable nature of cardiac tissue and to simulate the propagation of action potentials, while the complex Ginzburg-Landau equations capture the chaotic dynamics associated with arrhythmic conditions. A simplified…

Ectopia cordis is a rare congenital malformation in which the heart is partially or completely located outside the thoracic cavity. Most cases present in infancy with severe cardiorespiratory compromise. We report an exceptionally rare presentation of ectopia cordis interna, in which a structurally normal heart is located entirely within the upper abdomen, discovered incidentally in an asymptomatic young adult male undergoing evaluation for a respiratory infection. This case highlights the…
