Atrio-ventricular (AV) node located on the right side of inter-atrial septum.

Bundle of His: Thick cable of fibers starting at the AV node, bifurcating into left and right bundle branches (Lbb & Rbb) down the two sides of inter-ventricular septum, LEE bifurcates into anterior and posterior divisions or fescicles.

Purkinje fibers: Network of fibers at end of bundle of His that transmits impulse to both ventricular walls.
