| Abstract: | This paper develops numerical techniques for two problems of interest in electrocardiography: (1) the determination of infinite-media
surface potential gradients from boundedmedia torso potentials, and (2) the effects of lung-torso, blood mass-torso, and torso-air
conductivity interfaces on torso surface potentials. This paper is an extension of a previous paper on the effects of conductivity
interfaces which also utilized an integral equation formulation of Laplace's equation.
