(FIT)-Module 4 Workshop 7: Electrocradiogrpahic and Electrophysiological Correlations, Atrial Fibrillation, Clinical Scenarios and Syndromes-Gerstenfeld Case 4 Question

Video Transcription

Video Summary

A 40-year-old woman undergoes an EP study to investigate palpitations, revealing a supraventricular tachycardia induced via atrial programmed stimulation. The options for the tachycardia mechanism are atrial tachycardia, AV node re-entry, AV re-entry, or needing more information to determine the cause. The presentation includes a HISS signal visible on the HISS catheter. The key question is whether the information provided allows for a definitive conclusion about the tachycardia's mechanism, or if additional maneuvers and details are required for a precise diagnosis.
