The Impact of Automatic Threshold Tracking on Pulse Generator Longevity in Patients with Different Chronic Stimulation Thresholds
Why the study?
Does the Autocapture feature improve pulse generator longevity in patients with pacemakers?
Population
80 patients (mean age 79 +/- 9 years; 37 men, 43 women) with Pacesetter Regency SR+ pacemakers.
Comparison
Autocapture feature programmed On vs Autocapture programmed Off, and theoretical…

Implication
May extend modeled device longevity across thresholds; leaves open prospective confirmation before changing practice.

P
Population
80 patients (mean age 79 +/- 9 years; 37 men, 43 women) with Pacesetter Regency SR+ pacemakers.
I
Intervention
Autocapture feature programmed On
C
Comparator
Autocapture programmed Off, and theoretical calculations with stimulation voltage programmed at twice pacing threshold or minimum 2.4 V
O
Outcome
Theoretical pulse generator longevitysurrogate
Automatic threshold tracking (Autocapture) markedly prolongs theoretical pulse generator longevity across a broad range of long-term pacing thresholds.
