Reduction of Right Ventricular Pacing Using the Feature Ventricular Intrinsic Preference (VIP)

Reduce Ventricular Pacing Using Ventricular Intrinsic Preference: VIP™ Study

The purpose of this study is to evaluate the efficacy of the VIP™ feature (available in dual chamber Victory® devices) to reduce unnecessary RV pacing, and to determine if patients with implanted SJM pacemakers will benefit by using VIP™ rather than only a programmed AV/PV delay.

Inclusion Criteria:

• Patient has been implanted with dual chamber SJM Victory® device with VIP™ for 1 month (± 2 weeks).
• At the time of pacemaker implant, VIP™ is programmed "OFF".
• At the time of enrollment, patient is paced in the RV ≤ 60% of the time.
• Patient is medically stable.

Exclusion Criteria:

• Patient has evidence of complete AV block, such that ventricular pacing would be required as part of the patient's routine management.
• Patient is indicated for AF Suppression.
• Patient has persistent or chronic atrial fibrillation.
• Patient is unable to comply with the follow-up visits due to geographical, psychological, or any other reasons.
• Patient is currently participating in another device research study.
• Patient is younger than 18 years of age.
• Patient is pregnant.
• Patients life expectancy is less than 12 months.
