👇Mahaim Tachycardia (Part 2 - Final): 1.Sinus Rhythm: Normal PR interval without delta waves. 2.Always Wide Complex Tachycardia: Typically presents with LBBB morphology due to exclusive antegrade conduction via Mahaim fibers. 3.Incremental Atrial Stimulation: Shows maximum preexcitation with a normal PR interval and LBBB morphology. 4.Long RP Tachycardia: Characterized by stable ventriculo-atrial conduction. 5.Post-Pacing Interval (PPI - TCL <100 ms ) when pacing from the RVA. 6.Mahaim Potential: Identified at the lateral tricuspid valve annulus, resembling a His-like signal. 7.Frequent Localization: Most commonly found along the lateral TV annulus. 8.Mapping: Targets the site of latest atrial activation corresponding to Mahaim fibers. 9.Ablation: Enjoy the Termination of tachycardia during energy application. 10.Post-Ablation Findings: Loss of preexcitation during isoproterenol or atrial pacing (indicating successful elimination of Mahaim fibers). #VideoEducativo 🔗 @melhamriti
