Abstract
In this work we study the influence of a volume conductor on the orientation of cardiac currents that generate magnetic field. Previous computer simulations have suggested currents to be transversal to the local action potential propagation direction [4, 5]. Here we propose a new 2D model that accounts for the presence of a volume conductor in contact with a thin cardiac tissue. Our results using this tridomain model suggest that while part of the current spreads out to the volume conductor the orientation of the current in the cardiac tissue tends to align to the local cardiac fiber distribution.
