Electrocardiographic features and ablation outcomes of near-Hisian idiopathic ventricular arrhythmias: Insights from a single-center study in Vietnam.
Article in The Journal of international medical research, 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
ObjectiveTo compare the clinical characteristics, electrocardiographic characteristics, and outcomes of radiofrequency catheter ablation in patients with idiopathic right ventricular outflow tract ventricular arrhythmias originating near the Hisian bundle region versus other right ventricular outflow tract regions.MethodsA single-center study analyzed 126 patients undergoing radiofrequency catheter ablation for right ventricular outflow tract ventricular arrhythmias from May 2020 to October 2022. Patients were classified into the near-Hisian group (n = 10) and the right ventricular outflow tract group (n = 116) based on the arrhythmia origin. Clinical, electrocardiographic, and procedural characteristics as well as ablation outcomes were compared.ResultsThe near-Hisian group had narrower QRS duration (132.3 ± 24.1 vs. 146.1 ± 28.3 ms), 100% positive QRS in lead I, smaller R-wave ratio in leads III/II (0.65 ± 0.20 vs. 0.97 ± 0.31), smaller Q-wave ratio in leads aVL/aVR (0.31 ± 0.29 vs. 1.03 ± 0.37), and larger R/S ratio in lead V2 (18.8 ± 10.9 vs. 12.0 ± 6.7) (all p < 0.05). Procedural metrics, acute success (90%), and long-term success (80%) were comparable between the two groups, with no major complications reported.ConclusionsRight ventricular outflow tract ventricular arrhythmias near the Hisian bundle region have distinct electrocardiographic features. Radiofrequency catheter ablation is safe and effective, emphasizing the need for precise electrocardiogram interpretation and meticulous procedural planning.
