Mapping Six Decades of Research and Innovation in Cardiac Electrophysiology: A Historical Scientometrics Analysis.
Article in Journal of multidisciplinary healthcare, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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: Cardiac electrophysiology research has expanded rapidly, yet its global distribution, collaborative dynamics, and thematic evolution have never been quantified across the full history of the field. Mapping these patterns is crucial for guiding funding and designing impactful studies. Methods: A scientometrics analysis was conducted on articles indexed in Scopus, Web of Science, and PubMed (1959-2025). After screening, 3766 peer-reviewed papers were analyzed. Publication trends, citation-based indicators (h-index, which reflects productivity and impact; g-index, which highlights highly cited work; and m-index, which adjusts for time), journal quartiles, World Bank income-levels, and WHO regions were quantified. Co-authorship networks mapped institutional and national partnerships, while text-mining tracked keyword trajectories to identify emerging research fronts. Results: Annual publications increased from 3 in 1959 to 268 in 2021. Articles averaged six co-authors, with 25% showing international collaboration. High-income countries produced 86.7% of output and dominated journals' impact (mean h-index = 155). In contrast, lower-middle-income nations contributed only 1.9%. The University of California and the United States were central collaboration hubs, while Africa and Latin America remained peripheral. Keyword analysis showed a shift from pharmacology and in-vitro biophysics to newer areas such as implantable devices, artificial intelligence-guided risk scoring, and stem cell-based models. Emerging concepts such as Bayes theorem (for probabilistic modeling) and quantitative trait locus (for linking genetics to arrhythmia risk) are beginning to appear, though still scarcely represented. Cross-continental papers received the highest citation density. Conclusion: Cardiac electrophysiology knowledge is concentrated in high-income regions and in teams with strong collaboration. This map highlights geographic blind spots and emerging themes, offering a practical guide for building north-south consortia, focusing on neglected pathologies, and investing in artificial intelligence and stem-cell-based strategies likely to drive the next breakthroughs.
