___ ___ node is a group of cells positioned on the wall of the right atrium, near the entrance of the superior vena cava.
The ___________ _________ node is an area of specialized tissue between the atria and the ventricles of the heart, specifically in the posteroinferior region of the interatrial septum near the opening of the coronary sinus, which conducts the normal electrical impulse from the atria to the ventricles.
