In the region of the atrioventricular node a characteristic cell potential was obtained by microelectrode recording in dogs. The resting and action potentials obtained here were small and the latter had a step-like potential before the steepest rise. The site of origin was examined histologically by a special staining technic and was found to be from a cell of the atrioventricular node or a part of the special junctional tissue adjacent to it.
