摘要
目的了解近20年心电图Tp-Te间期的研究进展,探索当下的研究热点及未来的研究方向。方法在中国期刊全文数据库和Web of Science数据库核心合集中,以“Tp-Te”或“Tp-e”为篇目检索词,检索2002-01-01至2021-12-31这20年间发表的相关文献。采用Excel 2019及文献计量分析软件VOSviewer 1.6.17进行文献分类、关键词聚类,并对国家和机构合作及其时序变化等进行可视化分析,绘制相应的图谱。结果从两个数据库中分别获取414篇中文文献和669篇英文文献。相关中文文献数量在2006年以后明显递增,2017年达到峰值,此后发文数量趋于平稳;英文文献在统计时段内共出现2次峰值,分别是2006、2021年,且从2009年起基本呈递增趋势。发文量大的为固定的数种期刊,且发文量相差不大。英文文献国家聚类图中,土耳其虽然发文量多,但是与其他国家的合作并不多;与其他国家合作最多的是美国,其次是中国。发文的各机构间无明显密切合作。关键词聚类分析显示,中文文献以室性心律失常为主的相关研究较多,且在2016年后慢性心力衰竭、急性心肌梗死和急性冠脉综合征等研究主题趋热,对临床用药也有涉及;英文文献涵盖了长QT间期、Tp-e/QT、死亡率、猝死、P波离散度、肥胖以及新型冠状病毒肺炎等。结论我国Tp-Te间期相关的研究热点与其他国家有较大不同,这与国情、生活环境、社会现状及体质差异有关。
Objective To understand the research advances of ECG Tp-Te interval in the past 20 years,and to explore its current research hot spots and future research directions.Methods From the China Journal Fulltext Database and Web of Science Database,we searched the related literature with“Tp-Te”or“Tp-e”as article search words published in the past 20 years from 2002-01-01 to 2021-12-31.Excel 2019 and bibliometric analysis software VOSviewer 1.6.17 were applied in the literature classification,clustering of key words,and visualization analysis of countries,institutional cooperation and their sequential variation.Maps were correspondingly drawn.Results A total of 414 Chinese and 669 English papers are retrieved from the two databases,respectively.The number of related Chinese literature has shown an obvious and progressive increase after 2006,reaching the peak in 2017.Since then,the number of publications has leveled off.Literature in English shows two peaks in all during the statistics period,separately in 2006 and 2021;the number of literature approximately shows an incremental trend from 2009.A large number of related articles are published in several fixed journals without significant difference in the number of published articles.In the national clustering diagram of English literature,Turkey,although publishing a large number of papers,has no much cooperation with other countries;the United States has the most cooperation with other countries,followed by China.There is no obvious close cooperation between institutions which published the literature.Key word clustering analysis reveals that the Chinese literature mostly focuses on ventricular arrhythmias.The research topics trend towards chronic heart failure,acute myocardial infarction,acute coronary syndrome,etc.after 2016,and also involve clinical use of drugs.English literature covers long QT interval,Tp-e/QT,mortality,sudden death,P-wave dispersion,obesity,corona virus disease 2019 and so on.Conclusion Domestic research hot spots related to Tp-Te interval are quite different from those in other countries,which is associated with national conditions,living environment,social status and physical differences.
