(FIT)-Module 2 Workshop 3: SVT Mechanisms and Maneuvers-Miller Case 6 Question

Video Transcription

Video Summary

A 13-year-old girl experiencing palpitations and lightheadedness, with a history of a repaired ventricular septal defect, underwent an electrophysiology study for potential ablation. The tracings indicate her symptoms align with either an atrioventricular accessory pathway, a fasciculoventricular pathway, a nodoventricular pathway, or a nodofascicular pathway. The recordings show sinus rhythm, incremental rate atrial pacing, and atrial extra stimuli, highlighting the onset of the QRS complexes. The assessment aims to interpret these findings to diagnose the specific type of pathway causing her symptoms.
