Summary

Most pacemakers are never reprogrammed after implantation. Optimizing pacemaker output settings significantly extends pulse generator longevity by over 19 months, offering a safe and cost-effective solution.

Area of Science:

  • Cardiology
  • Biomedical Engineering

Background:

  • Pacemaker implantation is common, but device settings are often not revisited.
  • Nominal manufacturer settings may not be optimal for individual patient needs.

Purpose of the Study:

  • To determine the rate of pacemaker reprogramming after implantation.
  • To assess the impact of optimized programming on pacemaker longevity.

Main Methods:

  • Sixty patients with Teletronics Reflex pacemakers were evaluated.
  • Telemetry assessed initial programming; capture thresholds were measured.
  • Pacemakers were reprogrammed with a 2-2.5:1 safety margin.

Main Results:

  • 95% of pacemakers were found to be at their original factory settings.

  • Reprogramming extended estimated pulse generator life by 19.7 months (35.5%).

    • Conclusions:

    • The majority of pacemakers remain un-reprogrammed post-implantation.
    • Optimized pacemaker programming is a safe, effective, and cost-efficient method to significantly prolong device longevity.
