Numerical simulation of atrial fibrillation and radiofrequency ablation
Abstract: The electrical activity of the heart is modeled by a nonlinear system of partial differential equations referred to as the Bidomain equations. In this talk, we will discuss how to solve this system numerically. In particular, we will discuss the geometry, discretization of the system, operator splitting, preconditioning and software. As an application of the software, we will discuss simulation of atrial fibrillation that can be efficiently cured by radiofrequency ablation.The problem of simulating radiofrequency ablation poses one unorthodox PDE problem that will be given particular attention. The problem is to incorporate a continuous stream of data into a problem originally defined as an initial boundary value problem.
