The majority of supraventricular tachycardia (SVT) consists of atrioventricular reentry tachycardia (AVRT) (N = 2,492, 65.0%) and atrioventricular nodal reentry tachycardia (AVNRT) (N = 1,075, 28.1%). The accessory pathway location was left-sided in 1,237(49.7%) and right-sided in 1,251(50.3%) of the 2,488 pathways. The VAs consist of premature ventricular contraction (PVC) (N = 597, 75.5%) and ventricular tachycardia (VT) (N = 194, 24.5%). The duration of follow-up ranged from 1 month to 1 year. The overall acute\/long-term success rate of RFCA was 96.4%\/92.2%, AVRT 97.8%\/93.5%, AVRT 99.3%\/95.0, PVC 98.1%\/92.2%, and VT 81.3%\/75.2%. Serious complications occurred in 29 patients (0.6%).\r\nConclusions: This present study shows that RFCA is effective and safe in the treatment of arrhythmias in Chinese pediatric patients, with a high success rate exceeding 90%, low recurrence rate, and significantly reduces the risk of complications. The success rate of left-sided pathway ablation is slightly higher than that of the right-sided pathway. There is no difference in the success rate of RFCA among children of different ages. It could be the first-line therapy in the majority of pediatric patients with SVT and\/or VAs.<\/jats:p>","DOI":"10.1532\/hsf.2837","type":"journal-article","created":{"date-parts":[[2020,3,11]],"date-time":"2020-03-11T18:24:13Z","timestamp":1583951053000},"page":"E114-E117","source":"Crossref","is-referenced-by-count":9,"title":["The Efficacy and Safety of Radiofrequency Catheter Ablation for Cardiac Arrhythmias in Pediatric Patients"],"prefix":"10.31083","volume":"23","author":[{"given":"Su","family":"Xinxing","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhou","family":"Jie","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhou","family":"Lu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bing","family":"He","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"16242","published-online":{"date-parts":[[2020,3,11]]},"container-title":["The Heart Surgery Forum"],"original-title":[],"link":[{"URL":"https:\/\/journal.hsforum.com\/index.php\/HSF\/article\/download\/2837\/4373","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journal.hsforum.com\/index.php\/HSF\/article\/download\/2837\/4373","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,12,22]],"date-time":"2025-12-22T10:14:53Z","timestamp":1766398493000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.imrpress.com\/journal\/HSF\/23\/2\/10.1532\/hsf.2837"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,3,11]]},"references-count":0,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2020,3,4]]}},"URL":"https:\/\/doi.org\/10.1532\/hsf.2837","relation":{},"ISSN":["1522-6662","1098-3511"],"issn-type":[{"value":"1522-6662","type":"electronic"},{"value":"1098-3511","type":"print"}],"subject":[],"published":{"date-parts":[[2020,3,11]]}}}
