The Arbitrary Electromotive Double Layer in the Eccentric ``Heart'' of the Nonhomogeneous Circular Lamina

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.
