Leadless Pacing and Cardioversion: Power On or Power Off?
Article in JACC. Case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAtrial leadless pacemakers have recently been introduced as an alternative to conventional systems. CASE SUMMARY: An 86-year-old patient with sinus node dysfunction received a leadless atrial pacemaker. After cardioversion for persistent atrial fibrillation, device interrogation indicated an unexpectedly short battery longevity of only 9 months, despite minimal pacing. Repeat interrogation after 7 days demonstrated recovery of battery life to 6.1 years, suggesting a transient miscalculation. DISCUSSION: This case demonstrates that electromagnetic interference from electrical cardioversion can induce a power-on reset (PoR) mode in the Aveir AR pacemaker (Abbott), accompanied by a reset alert. Although PoR briefly interrupts device function, the system resumes normal operation within seconds, retaining programmed settings without reverting to safety mode or requiring reprogramming. Such transient resets may cause false estimates of battery depletion but do not reflect true malfunction. TAKE-HOME MESSAGES: PoR after cardioversion can transiently alter battery readings, but settings recover automatically. Recognizing PoR helps avoid misinterpretation and unnecessary interventions.
