Why the study?
Do cycles of repetitive P wave undersensing occur in the absence of PVARP extension in patients with dual chamber pacemakers and prolonged AV conduction?
Do cycles of repetitive P wave undersensing occur in the absence of PVARP extension in patients with dual chamber pacemakers and prolonged AV conduction?
Patients with dual chamber pacemakers and prolonged native AV conduction are prone to repetitive P wave undersensing and output inhibition, which may be mitigated by programming short AV intervals and PVARP.

Draft 1:* Suggests programming shorter AV intervals and PVARP may mitigate symptomatic.
