This paper focuses on the inverse ElectroCardioGraphy problem which consists in recovering the electrical potential and flux on the heart from electrical potential on the body surface. An energy-like error functional introduced in Andrieux et al. [3] and a generalized least-squares method are performed in the context of this ill-posed problem of missing boundary data recovering. Numerical experiments with 2D domains highlight the efficiency of the proposed methods as well as their robustness in the model context.
