Abstract

If the anisotropy ratios of the inner and outer domains of the myocardium are equal, then the volume distribution of cardiac sources can be replaced by an appropriate double layer on the heart surface. For an intramyocardial electrode there is an additional term proportional to the transmembrane potential.
