Description
Yohei Kikuchi and colleagues asked whether electrical signals measured before implanting an atrial leadless pacemaker predict pacing thresholds three months later. Thirty-nine consecutive patients received the Aveir AR device at one Japanese hospital between February and September 2025, mostly as part of dual-chamber systems. The primary outcome was atrial capture threshold at three months.
Premapping pacing threshold tracked with the three-month threshold, but the link was confounded by operator-driven site selection and was not an independent predictor. Waveform measures such as amplitude, current of injury, and voltage change added no further discrimination. Atrial tissue and anchoring differ enough from ventricular pacing that dedicated prospective markers are needed.
