    Notes: Abstract A method of investigating the electric field of the isolated perfused animal's heart in a liquid volume conductor is described. Potentials are recorded from 241 points on a spherical surface surounding the heart by a unipolar technique. The electrodes are 1–2 cm away from the surface of the heart. The leads are grouped together 6 at a time. One of them is recorded as a constituent of all groups and serves for synchronization. The method is intended for the study of various types of equivalent electrical generators of the heart.

    Notes: Abstract The relative contribution of the various multipolar components to the total surface potential was determined in experiments on the isolated heart located in a spherical volume conductor. These contributions were calculated for distances from the electrodes to the center of the cardiac ventricles that corresponded to the placement of standard and thoracic ECG recording electrodes in different age groups. On the basis of these results the optimal model of an equivalent cardiac generator can be chosen for a given electrocardiographic recording system.
