Editing Atrioventricular node (section)

===Location===
The AV node lies at the lower back section of the [[interatrial septum]] near the opening of the [[coronary sinus]], which conducts the normal electrical impulse from the atria to the ventricles. The AV node is quite compact (~1 x 3 x 5&nbsp;mm).<ref name="medical-dictionary.thefreedictionary.com"/> It is located at the center of [[Koch's triangle]]—a triangle enclosed by the septal leaflet of the tricuspid valve, the coronary sinus, and the membranous part of the interatrial septum.<ref>[http://www.accessmedicine.com/content.aspx?aID=2874462 Harrison's Principles of Internal Medicine, 17e" Section 3: Disorders of Rhythm] {{webarchive |url=https://web.archive.org/web/20110707080333/http://www.accessmedicine.com/content.aspx?aID=2874462 |date=July 7, 2011 }}</ref>
