A small area of special tissue in the right atrium called the sinoatrial (SA) node starts an electrical impulse (it's like the heart's spark plug) that will eventually travel down special electrical tracts (AV node, Bundle Branches, Purkinje Fibers — the heart's «wiring») within the heart and cause the heart muscle to contract (see Figure 2 below).
