    TITLE: Relative acceleration approach in the study on cardiac electric signal propagation

    ABSTRACT: In the heart, electrical signal propagates to cause the induction of calcium ions into cardiac cells for muscular contraction and subsequently for pumping oxygenated blood to all the body cells. Understanding the general behaviour of the cardiac electric signal, or cardiac wave in physical sense, is crucial for a host of cardiac pathologies, especially for atrial fibrillation, but the large part of its behaviour remains unknown: the first reason is the uniqueness of the cardiac wave which does not follow any kind of conservational laws in one domain because the heart tissue provides a dual space for the electric propagation in views that every point means each point in two different spaces. In addition, the prevalence of anisotropy and inhomogeneity on the curved surface of non-uniform curvature makes the problem even harder. To overcome these issues, the relative acceleration approach has been recently proposed which is borrowed from the classical studies of gravitations and relativity. In this talk, I'll present the hypothesis and proposition of this approach which implicitly implies that the governing diffusion-reaction equation is an projection of Maxwell's equations with a new gauge choice.
