Pacemaker
The heart's natural pacemaker is the sinoatrial (SA) node. The SA node sends an electrical impulse through both atria, pausing at the atrioventricular (AV) node, which is a small mass of cardiac muscle. To restore normal rhythm in the case of a block, an artificial cardiac pacemaker can be implanted in the chest.
