Vagal stimulation induces conduction block at coupling heterogeneities. A: Propagation during normal vagal tonus. For gmin=0.11 and Δg=0.69, a wave initiated in the distal end penetrates into the proximal PV. B: Increased vagal tonus, modeled by doubling IK1, leads to conduction block at the interface between normal and reduced conduction.
