In this paper, using the art model in cardiac electrophysi-ology, the monodomain model, which describes the electrical activity in cardiac tissue, we prove a stability estimates of parameters identification problem. For this purpuse, we first establish a Carleman estimate for the coupled heart-torso system. By means of this estimation and following the Bukhgeim-klibaniv method we prove our main result which is a Lipschitz stability estimate of conductivities parameters.
