Abstract:
The spreading of excitation in ventricular myocardium is modelled by treating the thin region of rapidly depolarizing tissue as a propagating wavefront. The model determines tissue excitation time using an eikonal equation that includes the effects of wavefront orientation in the myocardial structure and wavefront curvature. Use of a Petrov-Galerkin finite element method with a no-inflow boundary condition enables the eikonal equation to be solved on reasonably coarse meshes of cubic Hermite elements. The method is applied successfully on a model of the complete canine ventricular myocardium
