Do we need to enforce the homogeneous Neumann condition on the torso for solving the inverse electrocardiographic problem?
Abstract : Robust calculations of the inverse electrocardiographic
problem may require accurate specification of boundary
conditions at the torso and cardiac surfaces. In particular,
the numerical specification of the no-flux condition on
the torso is difficult because surface normals must be computed,
and because the torso may alternatively be considered
infinitely far away from the heart. Using the method of
fundamental solutions (MFS), this boundary
conditions can be taken into account in different manners.
Specifically, the no-flux condition on the torso can be
ignored, or weighted with respect to the Dirichlet boundary
condition associated to the torso data, or can be
strongly enforced through a saddle-point problem.
In this work we provide a preliminary comparison of
these different strategies.
