SA node (Sinus Node)
The primary pacemaker of a normal healthy heart is the sinus node (or SA node). It is located in the right atria of the heart.
The SA node is the "pacemaker" of the heart. Cells in the SA node are called "pacemaker" cells and they direct the contraction rate of the entire heart by generating action potentials.
