Abstract

The magnitude and direction of the spatial dipole moments of hearts of a dog, monkey and lamb were obtained in vivo from, multiple potentials on the body surface. A comparison between peak dipole moment and body weight in mammals showed a definite relationship. A comparison with spatial vectors calculated from the equilateral tetrahedron system showed significant differences. Graphs of instantaneous potential distributions around the chest showed that bidipolar conditions existed at certain times and locations, but the distributions were mostly unidipolar. Frontal plane angles calculated from the Einthoven triangle were about 30° too high, on the average.
