Why do AV nodal cells NOT determine the heart rate under normal circumstances?

B) They slow conduction of the wave of excitation.
C) They depolarize faster than all other conducting fibers.
D) They depolarize slower than all other conducting fibers.
E) The AV node is connected to the SA node, but not to other conducting fibers in the heart.
