(FIT)-Module 3 Workshop 4: SVT and VT Invasive and Non-Invasive Correlation-Miles Case 2 Answer

Video Transcription

Video Summary

The video discusses a case needing slow pathway ablation due to dual AV nodal pathway conduction, not atrial tachycardia or fibrillation. The patient displays one-to-two conduction via fast and slow AV nodal pathways without typical AV node reentry. Absence of retrograde fast conduction prevents echo beats or reentry induction. Some mistaken cases, seen as PSVT or atrial fibrillation, warrant slow pathway ablation instead. EKGs show RR alternans, with more QRS complexes than P waves, indicating non-reentrant dual AV node tachycardia, often misidentified as atrial fibrillation.
