Description
N Augustin and co-authors track, in a 2026 study, how pacing thresholds evolve after implantation of a leadless pacemaker in the heart's upper chamber. The atrial device, approved in Germany in 2024, pairs with a ventricular unit to form a fully leadless two-chamber system. Thresholds at implant looked high even when positioning seemed perfect.
Fourteen patients implanted between August 2024 and October 2025 were compared with fifty recipients of the matching ventricular device. Atrial thresholds started significantly higher than ventricular ones, then fell markedly and settled at low, stable levels over six months. Ventricular thresholds barely changed. The authors blame swelling at the contact point, proportionally larger in the small upper chamber, and call for work on the mechanism.
