   Abstract:
   The noninvasive measurement of electrical potentials at the surface of the body (e.g. the electrocardiogram) has long been considered an important tool in clinical diagnosis. Electrophysiological modeling and simulation are valuable aids in the interpretation of such potential recordings. In all cases the potential field can be considered to arise from bioelectric sources operating in a volume conductor. The appropriate quantitative formulation for these sources is emphasized. Such sources arise from excitable cells undergoing action potentials (primary sources) or at passive boundaries between regions of different conductivity (secondary sources). These sources are described and discussed for arbitrary cell shapes, circular cylindrical cells, conductive media with piecewise constant conductivity, and for syncytial tissue whose macroscopic properties are anisotropic
