This is correct. Suggest adding explanation to “Extra” that AV nodal artery can arise from RCA or LCA depending on R/L dominance. Heart<!-- --> - <!-- -->Knowledge<!-- --> @ AMBOSS
AMBOSS: Supplied by the AV nodal artery (posterior descending artery of right coronary artery)
SA node AMBOSS = Supplied by sinus node artery (branch of the right coronary artery)
i think the main point is the main artery that comes it comes off of, that is more high yield
