(FIT)-Module 3 Workshop 5: Invasive and Non-Invasive Correlation-Marchlinski Case 7 Question

Video Transcription

Video Summary

The case discusses initiating a wide complex tachycardia through burst pacing from the right ventricular apex, exploring various arrhythmia mechanisms. Choices include focal ventricular tachycardia from the parahisian region, bundle branch re-entrant ventricular tachycardia, atrioventricular nodal re-entry with a right bundle branch block pattern, and an accessory pathway mediated tachycardia with the same pattern. After considering initiation and entrainment pacing effects on the QRS complex and integrating intracardiac recordings, the correct response must be selected based on these observations.
