Benefits in Projected Pacemaker Longevity and in Pacing Related Costs Conferred by Automatic Threshold Tracking
Key result
The Autocapture function was projected to increase pacemaker longevity by 53% to 245% and reduce pacing-related costs by 25% to 57% over 15 years compared to standard settings.

Implication
Projected longevity and cost benefits with Autocapture should not yet alter VVIR practice; leaves open need for randomized confirmation.

Does automatic threshold tracking improve projected pacemaker longevity and reduce pacing related costs in patients with VVIR pacemakers?
P
Population
25 patients with a VVIR pacemaker featuring Autocapture, analyzed to project device longevity and costs over a 15-year follow-up.
E
Exposure
Automatic adaptation of device output coupled with continuously monitored capture threshold (Autocapture)
C
Comparator
Standard Output (5 V) and Low Output settings of the same device, and standard devices without Autocapture
O

Main Result
Effect estimate: 53% to 245% increase in longevity; 25% to 57% reduction in costs
Automatic threshold tracking in pacemakers significantly increases projected battery longevity and reduces pacing-related costs compared to standard fixed-output settings.
Cite This Study
Boriani et al. (2000) conducted an observational in Patients requiring a VVIR pacemaker (n=25). Autocapture function (automatic adaptation of stimulation output) vs. Standard Output (5 V) settings / standard device was evaluated on Projected pacemaker longevity and pacing related costs (53% to 245% increase in longevity; 25% to 57% reduction in costs). The Autocapture function was projected to increase pacemaker longevity by 53% to 245% and reduce pacing-related costs by 25% to 57% over 15 years compared to standard settings.
