One month post\u2010surgery, he presented with syncope and incessant ventricular tachycardia (VT), progressing to cardiogenic shock, which required emergency intra\u2010aortic balloon pump (IABP) support. The VT proved refractory to standard clinical management and demonstrated responsiveness only after IABP support. An electrophysiological study was conducted; however, VT could not be induced during the procedure. Through electrophysiological maneuvers, we suspected bundle branch reentrant ventricular tachycardia (BBR\u2010VT), and successful treatment was achieved via right bundle branch (RBB) ablation.<\/jats:p>","DOI":"10.1111\/pace.15192","type":"journal-article","created":{"date-parts":[[2025,4,26]],"date-time":"2025-04-26T09:26:52Z","timestamp":1745659612000},"page":"598-602","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Arrhythmic
