This preliminary study demonstrates that the conduction velocity in the venae cavae and the stimulation threshold and refractory period of the venae cavae, azygos and pulmonary veins in dogs were very similar to those found in atrial muscle. It is quite likely that atrial muscle extends for a distance into these veins and that the muscle receives vagal innervation. Superior vena caval pacing was performed in 1 patient.
