Hotspots and Frontiers in Arrhythmias During Pregnancy: A Bibliometric Analysis.

Background: Arrhythmias in pregnancy have become an increasingly significant concern for maternal and fetal well-being, reflecting a rising prevalence trend. This bibliometric analysis sought to delineate global research trajectories, pinpoint principal contributors, and underscore nascent areas of interest in this domain. Methods: We retrieved publications concerning arrhythmias in pregnant women from 1996 to 2025 from the Web of Science Core Collection. A bibliometric analysis was performed utilizing VOSviewer, CiteSpace, and the R package "bibliometrix" to delineate co-authorship networks, institutional collaborations, and patterns of keyword co-occurrence. Results: In total, 1042 publications were identified with an annual growth rate of 4.9%. The USA led in total publications (300, 28.8%). Productive institutions featured the University of Toronto (95) and Harvard University (94). The American Journal of Cardiology contributed the highest number of articles (25). Roos-Hesselink JW was identified as a foremost researcher, with 23 publications and an H-index of 19. Keyword analysis revealed "management" as a central theme, while "outcome", "long QT syndrome", and "cardiovascular disease" were emerging themes. Conclusion: This bibliometric study presents a thorough overview of international research on arrhythmias in pregnant women. It identifies key contributors, influential institutions, and developing research topics, offering potential insights for optimizing pregnancy management, enhancing clinical outcomes, and progressing the treatment of cardiovascular and heart-related conditions during gestation.
