Claim Text:
1. A method of promoting an atrial-based pacing modality, comprising the steps of: pacing an atrial chamber of a heart pursuant to an atrial-based pacing modality; detecting a ventricular response from the pacing; and based on a predetermined criteria, determining whether a relatively reliable AV conduction condition exists: if the relatively reliable conduction condition is present, continuing the atrial-based pacing modality, and if the relatively reliable conduction condition is not present, switching to a dual-chamber pacing modality; in the event that the ventricular response is a PVC, switching the pacing modality to a dual-chamber pacing modality for at least one cardiac cycle or for a predetermined period of time; determining a number of pacing modality switches that have occurred during the predetermined period of time; and in the event that the number of pacing modality switches exceeds a predetermined threshold number, then continuing the dual-chamber pacing modality without performing a step of determining whether relatively reliable AV conduction condition is present and discontinuing the pacing modality switching, and
