   Abstract:
   Potentials generated by live turtle (pseudemys) heart at center of spherical electrolytic tank were measured at surface points; using truncated multipole expansion, dipole and quadrupole coefficients were determined from resultant set of simultaneous equations at intervals over QRS period; measurement technique was checked using known artificial sources; rough check on truncation assumptions was made based on known analytical model; experimental results show that significant quadrupole term is present; presence of higher order poles could not be ruled out.
