Conduction System Pacing-Induced Ventricular Arrhythmia: Case Report.
Article in Annals of noninvasive electrocardiology : the official journal of the International Society for Holter and Noninvasive Electrocardiology, Inc, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Left bundle branch-optimized cardiac resynchronization therapy (LOT-CRT), combining left bundle branch area pacing (LBBAP) with a left ventricular lead, offers physiological activation and improved synchrony compared with conventional biventricular pacing. We report a 78-year-old woman with pacing-induced cardiomyopathy who underwent LOT-CRT, resulting in QRS narrowing but notable QT prolongation and T-wave inversions. On the first post-implant day, she developed ventricular fibrillation triggered by premature ventricular complexes, without reversible metabolic or ischemic cause. This case highlights the potential for early post-procedural ventricular arrhythmias in structurally compromised ventricles, underscoring the importance of vigilant monitoring and individualized risk assessment following LOT-CRT.
