    The multipole expansion of the cardiac generator in precordial leads offers a rough approximation. Adding higher-order multipoles minimally improves accuracy, suggesting limited clinical electrocardiography prospects.

    Area of Science:

    • Biophysics
    • Electrophysiology

    Context:

    • Investigating the electric field of an isolated dog heart in a liquid conductor.
    • Analyzing the accuracy of multipole equivalent generators for cardiac electrical activity.

    Purpose:

    • To quantitatively describe the cardiac generator using multipole expansion.
    • To assess the clinical applicability of multipole models in electrocardiography.

    Summary:

    • Measurements indicate that a 1st-order multipole (dipole) is a rough approximation for the cardiac generator in precordial leads.
    • Including a 2nd-order multipole (quadripole) offers only a marginal increase in descriptive accuracy.
    • The multipole expansion converges slowly for this problem, limiting its utility.

    Impact:
