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

Video Transcription

Video Summary

The procedure describes an ablation targeting an atriofascicular pathway involved in antidromic tachycardia. Focus is placed on the lateral tricuspid annulus to disrupt this accessory AV node pathway, which travels through the right free wall. Ablating near the ventricular insertion is avoided to prevent a right bundle branch block, which could complicate and prolong the tachycardia circuit. Identifying hys bundle-like potentials along the tricuspid annulus is key, as targeting these can interrupt the abnormal conduction pathway effectively without adversely affecting the heart's electrical system.
