Abstract
A formulation of the bidomain model is presented for analysis of the e xtracellular electric and magnetic fields of the excitable myocardium with the use of relationships of the stationary current electrodynamic s. Definitions of equivalent generator of extracellular field and equi valent medium are given, taking into account the macroscopic anisotrop y of the tissue. The model described serves as it basis for solving th eoretical and practical problems of heart state estimation from noninv asive measurements of its electric and magnetic fields.
