Abstract :
The potential is described everywhere for a nonhomogeneous circular lamina which simulates a transverse section through the chest at the ventricular level. The field is generated by an arbitrary electromotive double layer in the wall of the eccentric ``heart.´´ The field may be made dipolar (or nondipolar) with or without axial symmetry. Specific resistivities may be assigned to ``heart-cavity blood,´´ to ``heart wall,´´ to ``pericardial fluid,´´ to ``lung region,´´ to ``torso-shell´´ or ``chest wall´´ and to the medium exterior to the ``body.´´ The size of various regions is arbitrary as is the eccentricity of ``heart center.´´ A particular case with axial symmetry is computed and the results are compared with appropriate model experimentation. The way is hereby opened to three-dimensional treatment.
