Editing Atrioventricular node (section)

===Blood supply===
The blood supply of the AV node is from the [[atrioventricular nodal branch]]. The origin of this artery is most commonly (80–90% of hearts) a branch of the [[right coronary artery]], with the remainder originating from the [[left circumflex artery]].<ref name="pmid5086972">{{Cite journal|vauthors=Van der Hauwaert LG, Stroobandt R, Verhaeghe L |title=Arterial blood supply of the atrioventricular node and main bundle |journal=British Heart Journal |volume=34 |issue=10 |pages=1045–1051 |date=October 1972 |pmid=5086972 |pmc=458545 |doi=10.1136/hrt.34.10.1045}}</ref><ref>{{Cite journal | last1 = Pejković | first1 = B. | last2 = Krajnc | first2 = I. | last3 = Anderhuber | first3 = F. | last4 = Kosutić | first4 = D. | title = Anatomical aspects of the arterial blood supply to the sinoatrial and atrioventricular nodes of the human heart | journal = The Journal of International Medical Research | volume = 36 | issue = 4 | pages = 691–698 | year = 2008 | pmid = 18652764 | doi=10.1177/147323000803600410| doi-access = free }}</ref><ref>{{Cite journal | last1 = Saremi | first1 = F. | last2 = Abolhoda | first2 = A. | last3 = Ashikyan | first3 = O. | last4 = Milliken | first4 = J.

In ''right-dominant'' individuals the blood supply is from the right coronary artery while in left dominant individuals it originates from the left circumflex artery.
