Abstract: Establishing the precise mechanism of cardiac arrhythmias in the electrophysiology laboratory is one of the main requisites for a successful and safe ablation. This article provides an organized approach to the differential diagnosis of narrow and wide complex tachycardias based on the analysis of electrical activation patterns, followed by specific pacing maneuvers in each case.<br />Competing Interests: Disclosures The authors have no conflicts of interest to disclose.<br /> (Copyright © 2024 Heart Rhythm Society.
