In the era of cardiac electrophysiology, catheter\u2010induced RBB block (CI\u2010RBBB) has become a common phenomenon observed during electrophysiological studies and catheter ablation procedures. While typically transient, it may persist for the entire procedure time. Compared to pre\u2010existing RBBB, the transient nature of CI\u2010RBBB allows for comparative analysis relative to the baseline rhythm. Furthermore, unlike functional RBBB, it occurs at similar heart rates, making the comparison of conduction intervals more reliable. While CI\u2010RBBB can provide valuable diagnostic information in various conditions, it is often overlooked by cardiac electrophysiologists. Though it is usually a benign and self\u2010limiting conduction defect, it may occasionally lead to diagnostic difficulties, pitfalls, or undesired consequences. Avoidance of CI\u2010RBBB is advised in the presence of baseline complete left bundle branch block and when approaching arrhythmic substrates linked to the right His\u2010Purkinje\u2010System, such as fasciculo\u2010ventricular pathways, bundle branch reentry, and right\u2010Purkinje focal ventricular arrhythmias. This article aims to provide a comprehensive practical review of the electrophysiological phenomena related to CI\u2010RBBB and its impact on the intrinsic conduction system and various arrhythmic substrates.<\/jats:p>","DOI":"10.1111\/jce.16050","type":"journal-article","created":{"date-parts":[[2023,9,1]],"date-time":"2023-09-01T13:38:21Z","timestamp":1693575501000},"page":"2316-2329","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Catheter\u2010induced
