Abstract

In this article we study the problem of estimating the parameters of an electrical model of the heart from a temporal recording of extracellular potentials. The chosen model is the reaction-diffusion model on the action potential proposed by Aliev and Panfilov. The strategy consists in building an error criterion based upon a comparison of depolarization fronts between the model and the measures. This error criterion is minimized by a global and then local adjustment of the model parameters. The feasibility of the approach is demonstrated on simulated and real measures on a canine heart.
