dc.description.abstractEnRobust calculations of the inverse electrocardiographicproblem may require accurate specification of boundaryconditions at the torso and cardiac surfaces. In particular,the numerical specification of the no-flux condition onthe torso is difficult because surface normals must be computed,and because the torso may alternatively be consideredinfinitely far away from the heart. Using the method offundamental solutions (MFS), this boundaryconditions can be taken into account in different manners.Specifically, the no-flux condition on the torso can beignored, or weighted with respect to the Dirichlet boundarycondition associated to the torso data, or can bestrongly enforced through a saddle-point problem. In this work we provide a preliminary comparison ofthese different strategies.
