A jump in the atrioventricular conduction curve is not caused by a switch from fast pathway to slow pathway conduction

Conclusion: Contrary to what has been assumed, a transition from FP to SP conduction does not produce a jump in the AV conduction curve. A jump in the AV conduction curve is most likely caused by the formation of intranodal/nodal–atrial reentry and its subsequent conduction.
