Abstract
An experimental technique is described for measuring the equivalent multipole model for isolated beating hearts. The dipole, quadripole, and octapole moments are measured from weighted sums of 20 electrode potentials on the surface of a 6.35-cm diameter sphere. An iterative procedure is used to eliminate the effects of source eccentricity for dipolar data.
