Battery longevity and His bundle lead performance in His bundle pacing.

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
Background: High capture thresholds and lead dislodgment are often cited as impediments for general adoption of His bundle pacing. Objective: We report on our experience in managing patients who underwent His bundle pacing with higher energy requirement and incidence of lead dislodgment in a mean duration of 33 months. Methods: In 1188 patients, pacing was done at the site of His bundle electrogram and capture of conduction axis was confirmed by paced complex demonstrating normal or more normal QRS voltage, QRS axis, and ventricular activation time. Patients were followed for 33 months with routine programming changes to optimize battery longevity. Results: His bundle pacing thresholds revealed a small but significant increase in His bundle capture (from 1.1 ± 0.8 to 1.3 ± 0.8 [ Conclusion: In His bundle pacing, the increase in capture threshold over time can be managed by optimizing pacing pulse duration and polarity. The dislodgment rates of Medtronic 3830 lead are not unlike those reported for myocardial pacing. Our study calls attention to the >2 V threshold in 16% of patients and the need for higher output pacemaker batteries.
