The RN presented as a shuttle shape and was the only tissue directly connected with the atrium in the anterior septum. The RN connects with the AVN anatomically, suggesting that direct electrical conduction occurs between them. The entrance of the atria into the AVN is distal to the RN, which may form the fast AVN pathway.
