title: The cancellation of mirror-image electrocardiograms in the horse.
abstract: The paper describes the use of a four-electrode cancellation technique, employing a bridge circuit to cancel mirror-image ECGs on the body surface of six horses. The axes joining points at which good cancellations were obtained were plotted on planar diagrams. Evidence is presented which suggests that a considerable proportion of cardiac activity could be regarded as though arising from the activity of a single resultant dipole although there is probably some mobility of the dipole centre during different parts of the cardiac cycle.
