How can it be that mathematics, being after all a product of human thought independent of experience, is so admirably adapted to the objects of reality? - Albert Einstein

    • Abstract :
      An arrhythmia is any disturbance from the normal periodicity of the heart beat, and alternans is one type of arrhythmia which can be a precursor to potentially fatal conditions of the heart. Dynamical systems have the ability to describe cardiac action potentials and are thus an invaluable tool in the pursuit to understand cardiac electrical activity. We developed a two-variable model as a modification of the popular Fitzhugh-Nagumo and Mitchell-Schaeffer models for electrical activity in excitable cells. Our model captures the major components of cardiac behavior while allowing for an explicit analysis of the propagation of electrical impulses in cardiac tissue. We examine the existence and stability of such traveling waves. Further, we use techniques of singular perturbation theory to derive and analyze an equation describing the onset and development of alternans in cardiac tissue.
