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

This study is currently recruiting participants.

Verified by St. Jude Medical, September 2007

Sponsored by:	St. Jude Medical
Information provided by:	St. Jude Medical
ClinicalTrials.gov Identifier:	NCT00311168

Purpose

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.

Eligibility

Ages Eligible for Study:	18 Years and older
Genders Eligible for Study:	Both
Accepts Healthy Volunteers:	No

Criteria

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.
