Key result
AutoCapture significantly extended estimated pacemaker longevity compared with nominal settings (103 vs 80 months, P<0.01), especially in patients with high pacing thresholds.
Why the study?

The AutoCapture algorithm significantly prolongs pacemaker battery longevity compared to nominal settings, particularly in patients with high pacing thresholds.
Chen et al. (2006) studied Pacemaker implantation (n=34). AutoCapture (AC) on vs. AC off with nominal output was evaluated on Estimated longevity in months (p=< 0.01). AutoCapture significantly extended estimated pacemaker longevity compared with nominal settings (103 vs 80 months, P<0.01), especially in patients with high pacing thresholds.
