A Case Report: Electrotonic Modulation-Related T-Wave Over-Sensing After Left Bundle Branch Pacing.
Article in Annals of noninvasive electrocardiology : the official journal of the International Society for Holter and Noninvasive Electrocardiology, Inc, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
A 66-year-old male patient diagnosed with dilated cardiomyopathy, heart failure with reduced EF (32%), and complete left bundle branch block (CLBBB) received cardiac resynchronization therapy (CRT)-D implantation. Left bundle branch pacing (LBBP) was successfully performed, but during the follow-up 6 weeks later, the electrocardiogram (ECG) showed a sinus rhythm tracked by ventricular pacing with a ratio of approximately 2:1 due to T-wave over-sensing, which might be caused by the changes in T-wave morphology due to electrotonic modulation and hyperkalemia or by the lower sensitivity threshold set by the auto sensing algorithm of the ICD. Shortening post-ventricular atrial refractory period (PVARP) restored the ventricular pacing tracking of the atrium, and the T-wave changes improved as time went by.
