Official Title: Complete Automatic Pacing Threshold Utilization Recorded by EnPulse

Further study details as provided by Medtronic Cardiac Rhythm and Heart Failure:

Primary Outcome Measures:
  • The automatic device features Atrial Capture Management and Ventricular Capture Management measure pacing thresholds and is compared to manual pacing thresholds observed at the 6 month follow-up visit

Secondary Outcome Measures:
  • Observe the variability of multiple pacing thresholds measured with ACM and VCM
  • Observe visit time differences using automatic measurements versus traditional follow-up
  • Observe the effects of Post Mode Switch Overdrive Pacing (PMOP) on AT/AF burden.

Estimated Enrollment: 860

Study Completion Date: September 2006
Primary Completion Date: September 2006 (Final data collection date for primary outcome measure)
Detailed Description:

The purpose(s) of the study is (are) to evaluate several features available in EnPulse Series pacemaker and report the long term benefit of Atrial Capture Management (ACM) and Ventricular Capture Management (VCM) as demonstrated by accuracy in comparison with manual measurements and variability of ACM and VCM thresholds.

In addition, an evaluation of the timesaving and qualitative benefits of the device feature known as Quick Look II (the computer interface screen of the device programmer) will be measured through the use of a questionnaire completed by the health care professionals involved in patient follow-up care.

This is a one-to-one randomized, multicenter, prospective study in which patients receiving new EnPulse pacemaker implants will be randomized to each of three study arms, 1) routine manual follow-up and follow-up using the automatic features; 2) ACM diagnostics detail on or VCM diagnostics detail on; 3) PMOP on / off or PMOP off / on (6 month cycle).
