Voltage-Gradient Mapping-Guided Slow Pathway Ablation in Typical Atrioventricular Nodal Re-Entrant Tachycardia.
Article in Pacing and clinical electrophysiology : PACE, 2025. 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
introductionHigh-density mapping is useful for common atrioventricular nodal re-entrant tachycardia (AVNRT) ablation. This study aimed to evaluate the effective targets for slow pathway (SP) ablation using voltage-gradient mapping.
methodsFifty-two patients diagnosed with slow/fast AVNRT were enrolled. Patients underwent SP ablation using either a voltage-gradient map (n = 20) or a conventional approach based on anatomic and electrophysiological findings (n = 32). The Ensite X EP system was used as the 3-D mapping system in all patients. The target CA site was defined as the location at which the Jackman potential, with a voltage of <0.5 mV on the tricuspid annulus (TA) side of the pivot point, was confirmed by the creation of a voltage-gradient map with the Advisor HD Grid SE.
resultsThe distance from the successful ablation site to the His bundle was significantly greater in the voltage-gradient map group (15.0 (12.8-19.0) vs. 11.0 (8.0-13.0) mm, p < 0.001), the junctional rhythm heart rate was slower (92.5 (78.8-121.8) vs. 114.0 (96.8-131.0) bpm, p = 0.028), and the time to the appearance of junctional rhythm after radiofrequency application was shorter (4.0 (2.5-7.3) vs. 7.8 (6.6-8.6) s, p = 0.002). Furthermore, the procedure time was also significantly shorter (53.5 (47.0-67.0) vs. 99.5 (76.3-112.5) min, p < 0.001) in the voltage-gradient map group.
conclusionThe site at which the Jackman potential was confirmed, with a voltage of <0.5 mV on the TA side from the pivot point drawn using the voltage-gradient map, may be defined as the CA target of SP.
