receives the action potential from the AV node
located in the upper wall of the right atrium
are large‐diameter fibers that conduct the action potential
located near the lower region of the interatrial septum,
transmits the impulse to the ventricles by way of the right and left bundle branches
initiates the cardiac cycle by generating an action potential that spreads through both atria through the gap junctions of the cardiac muscle fibers
receives the action potential generated by the SA node.
A slight delay of the electrical transmission occurs here, allowing the atria to fully contract before the action potential is passed on to the ventricles
the interventricular septum, down to the apex, and then upward through the ventricles
