Avascular necrosis (AVN) is defined as cellular death of bone components due to interruption of the blood supply. AV conduction during normal cardiac rhythm occurs through two different pathways: An important property that is unique to the AV node is decremental conduction,[12] in which the more frequently the node is stimulated the slower it conducts. Avascular necrosis of the hip is more common than other sites, presumably due to a combination of precarious blood supply and high loading when standing. [1] The AV node lies at the lower back section of the interatrial septum near the opening of the coronary sinus, and conducts the normal electrical impulse from the atria to the ventricles. It electrically connects the atria and ventricles.
