Current status and associated factors of intraoperative pain during radiofrequency catheter ablation for atrial fibrillation under conscious sedation: single-center experience.
Observational study in BMC cardiovascular disorders, 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
objectivesThis study was performed to evaluate the current status and to analyze the associated factors of intraoperative pain experience during radiofrequency ablation of atrial fibrillation (AF) with conscious sedation and analgesia.
methodsThis cross-sectional observational study employed convenience sampling of AF patients underwent their first radiofrequency ablation. General information questionnaire, intraoperative status sheet, Wong-Baker faces pain rating scale, hospital anxiety and depression scale, and the Connor-Davidson Resilience Scale were employed for data collection and analysis.
resultsA total of 428 patients (mean age 66.5 ± 9.6years; 59.8% male) were enrolled in this study. At ablation start, 62.9% of patients had moderate pain. When ablating specific regions, moderate pain and severe pain was encountered in 76.2% and 11.7% patients, respectively. Female patients had higher pain score than male patients at the followed 3 time-points: ablation start, ablating specific regions, and sheaths removal (z =-2.923, -4.349, -2.385, respectively, all P < 0.05). A negative correlation between the interoperative pain scales and the psychological resilience scales was confirmed at the time-point of before sedation, during ablation, ablating specific regions, and sheaths removal (r=-0.161, -0.464, -0.773, -0.352, respectively, all P < 0.05). Multivariable logistic regression analysis revealed that the strength and resilience dimensions of psychological resilience were significant protective factors against pain during radiofrequency ablation, with low levels of strength and tenacity associated with 2.32-fold and 2.17-fold increased risks of moderate pain, respectively, while optimism and clinical factors showed no significant effects.
conclusionMost of AF patients undergoing radiofrequency ablation with conscious sedation and analgesia experienced significant intraoperative pain experience, particularly when specific cardiac regions were ablated. Enhancing psychological resilience before the procedure may help reduce intraoperative pain scores.
