Why the study?
Is chronic ventricular pacing at an output amplitude of 1.0 V feasible and safe in patients with steroid-eluting leads who have capture at 0.5 V?

May support low-output pacing to extend longevity in select patients; hypothesis-generating and requires randomized confirmation.
Is chronic ventricular pacing at an output amplitude of 1.0 V feasible and safe in patients with steroid-eluting leads who have capture at 0.5 V?
Chronic ventricular pacing at an output amplitude of 1.0 V is feasible and safe in patients with steroid-eluting leads who have capture at 0.5 V, which may increase pacemaker longevity.
