The simulation of electrical activity of the heart is known to require a large number of non-linear stiff ordinary differential equations (ODEs) describing cellular physiology coupled with partial differential equations (PDEs) describing the flow of electricity through myocardial tissue.                                            My research considers a full study of the effects of mechano-electrical excitation on the propagation of the cardiac electric wave through detailed exploration of complex ionic models. In this project, the main emphasis is on practical development of numerical strategies and algorithms for implantable devices capable of preventing development and detrimental effects of cardiac alternans in a cardiac relevant anatomical model.  Electrical alternans is a physiological phenomenon that is a beat-to-beat oscillation (alternation) of the cardiac Action Potential Duration (APD). Alternans has been shown to be a precursor to arrhythmias and sudden cardiac death (SCD).  Computer simulations will be used to study the specific goals and this will be conducted with complex cell model dynamics and with 2D and 3D realistic anatomical models. Computer simulation studies will be realized by the Finite Element Method (FEM) and Finite Difference Method (FDM), with the use of advanced numerical techniques for the simulation of a coupled system of parabolic nonlinear partial differential equations (PDEs) and stiff ordinary differential equations (ODEs).
