Webjunctional foci (in the AV junction) normally have an intrinsic rate 40- 60bpm. ventricular foci normally have an intrinsic rate 20-40bpm. The reason that the nice regular rhythm generated by the SA node is not interupted by contractions generated by all these other pacemakers is that the SA node has the fastest intrinsic pacing rate.
