The RF delivery\u2010induced Supraventricular Tachycardia, persisting for a few minutes following the termination of ablation (post\u2010ablation SVT) was investigated in this research. Atrial Overdrive Pacing (AOP) was applied to the post\u2010ablation SVT to distinguish AVNRT from Junctional Tachycardia(JT). A total of 2337 RF\u2010current deliveries were applied, and post\u2010ablation SVT was observed in 81 of them. According to the electrophysiological studies, five of them (in five separate cases) were definitely diagnosed as JT. The overall incidence of post\u2010ablation JT was about 1% of all patients. In these cases, RF energy was applied to the posteroseptal region and roof of the proximal coronary sinus. The mean Cycle Length (CL) of JTs was equal to 446 \u00b167ms. Following post\u2010 ablation JT termination, four cases met endpoints of successful ablation, demonstrating a positive predictive value of 80%. Atrioventricular (AV) block did not occur in any of the cases and reappearance of JT was not observed during procedure or mean follow\u2010up period of 19.8 \u00b1 8.4 months.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Post\u2010ablation JT is probably a transient Ischemia\u2010induced arrhythmia that does not require further ablation. Thus, it is recommended to differentiate between the AVNRT and JT in post\u2010ablation arrhythmias to avoid unnecessary RF application.<\/jats:p><\/jats:sec>","DOI":"10.1111\/pace.14376","type":"journal-article","created":{"date-parts":[[2021,10,9]],"date-time":"2021-10-09T10:42:28Z","timestamp":1633776148000},"page":"2041-2045","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["The
