The atrioventricular (AV) node has two vitally important functions. One is its role in the conduction through atrium to ventricle. The slow conduction of excitation within the node [1, 2] provides an adequate time delay between the contraction of atria and that of ventricles and enables the heart to function as an efficient pump. Another function of the AV node is its secondary pacemaker activity. When the sinoatrial (SA) node fails to control cardiac rhythm, as a result either of depressed automaticity or impaired conduction, the AV node functions as a pacemaker of the heart.
