[Bidomain model for estimation of myocardial electric generators and extracellular fields].
A formulation of the bidomain model is presented for analysis of the extracellular electric and magnetic fields of the excitable myocardium with the use of relationships of the stationary current electrodynamics. Definitions of equivalent generator of extracellular field and equivalent medium are given, taking into account the macroscopic anisotropy of the tissue. The model described serves as a basis for solving theoretical and practical problems of heart state estimation from noninvasive measurements of its electric and magnetic fields.
