Assuming homogeneous conductivity and a limitless medium, a theoretic analysis accomplished by employing a model leads to the conclusion that dipole eccentricity produces a systematic error in the magnitude and direction of the instantaneous manifest vectors, the manifest QRS loops and the potential of the central terminal. Exaggeration of the electrical rotation of the heart and other electrocardiographic problems are discussed as possible manifestation of dipole eccentricity. Certain correlations applying to spatial vectorcardiography are made from simultaneous study of the theoretic back potential, the AP lead of the cube, and the potential of the central terminal.
