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

Video Transcription

Video Summary

A 57-year-old man experienced atrial tachycardia after thoracoscopic maze surgery for atrial fibrillation. During an EP study, overdrive pacing was conducted, and the tracing indicated a poor pace match, making the pacing site irrelevant for diagnosing atrial tachycardia. The tracing suggests that pacing inhibited a focal right atrial tachycardia. The pacing site is located within a diastolic corridor, indicating re-entrant atrial tachycardia, or there may have been a spontaneous change in the atrial tachycardia.
