Formation of the Wenckebach Periodicity in a Mathematical Model of Rabbit AV Node

Wenckebach periodicity (Mobitz type 1 second-degree AV block) originates in the atrioventricular node at fast regular rhythms. It is characterized by progressive prolongation of conduction time until a complete block, followed by restoration of the AV node, then the cycle repeats. Wenckebach periodi...

Summary:Wenckebach periodicity (Mobitz type 1 second-degree AV block) originates in the atrioventricular node at fast regular rhythms. It is characterized by progressive prolongation of conduction time until a complete block, followed by restoration of the AV node, then the cycle repeats. Wenckebach periodicity is a well-known clinical feature, but the underlying electrophysiology and, in particular, the role of the AV nodal dual pathways are not fully understood. This work considers some hidden peculiarities of Wenckebach phenomenon and its typical and atypical variants.
