A Bibliometric Study on Junctional Ectopic Tachycardia: Time and Trends have much to Tell!

Abstract

Junctional ectopic tachycardia (JET), an arrhythmia of substantial clinical relevance, is no less than an eternal nemesis in cardiac critical care. Hence, we hereby present a bibliometric study evaluating the research trends in the subject. A Scopus search-based bibliometric analysis of the keyword “Junctional Tachycardia” OR “Junctional Ectopic Tachycardia” restricted to original articles and reviews was undertaken after excluding the veterinary-related papers. The metadata thus obtained was analyzed using Scimago Graphica 1.0.42 and VOSviewer version 1.6.20 to generate a graphical representation of the trends and the timelines based on the author keywords. A total of 926 papers of interest were identified and selected for the analysis, which revealed the geographical distribution of productivity being primarily concentrated in the Western developed nations, topic receptiveness largely appreciated in cardiovascular-related journals, and increased yearly output of the JET-associated papers. Further perusal identified 79 most frequently observed author keywords when limited to a minimum of 5 co-occurrences, which were grouped into seven color-coded clusters by VOSviewer, and mapped into keyword as well as author network, overlay, and density projections. Bibliometric analysis of JET papers from 1967 to 2024 shows a growing interest in the topic, awaiting newer insights into the molecular mechanisms and the preventative treatment strategies.
