marcapaso natural

marcapaso natural

The heart's natural pacemaker, called the sinoatrial or S-A node, which is located in heart's upper right chamber, the right atrium. Electrical impulses originate in the S-A node, which causes the atria to contract, forcing blood into the heart's lower chambers, the ventricles.
