Background: The current report describes a manifestation of linking phenomenon in DDD pacemaker recipients: impairment of atrioventricular (AV) conduction and ensuing unnecessary right ventricular (RV) pacing.Methods: Three patients with second‐degree AV block and sudden impairment of native AV conduction following pacemaker implantation are presented. Loss of native AV conduction was considered functional and related to repetitive retrograde invasion of ventricular depolarization to the AV junction that was “linked” to ventricular pacing triggered by nonconducted P‐waves.Conclusion: This case series demonstrates that linking phenomenon should be considered in analysis of pacemaker behavior, and that retrograde concealment can be responsible for unnecessary RV pacing.
