(FIT)-Module 3 Workshop 4: SVT and VT Invasive and Non-Invasive Correlation-Miles Case 5 Question

Video Transcription

Video Summary

A 24-year-old male with recurrent wide QRS tachycardia, without structural heart disease, is being assessed for ablation. Treatment could target several areas, including the AV node's rightward inferior extension, the slow pathway, right bundle branch, lateral tricuspid annulus, or the sites of earliest activation during tachycardia. The discussion includes analyzing surface and intracardiac tracings during different heart rhythms, with specific attention to mapping during sinus rhythm and tachycardia using surface leads, HIST leads, a halo catheter along the tricuspid annulus, and a decapolar catheter in the coronary sinus.
