(FIT)-Module 5 Workshop 9: Arrhythmia Case Studies (Putting It All Together for the Boards)-Miller Case 5 Question

Video Transcription

Video Summary

A 37-year-old man with palpitations and lightheadedness undergoes an electrophysiology study after three failed ablation attempts. The discussion revolves around diagnosing the arrhythmia based on ECG and intracardiac recordings. The possible diagnoses considered include AV nodal reentry with lower common pathway block, sinus rhythm with 1:2 atrioventricular conduction, junctional tachycardia with left posterior fascicular block, fascicular tachycardia from the left anterior fascicle, or reentry within the His-Purkinje system. The baseline tracing and intracardiac recordings from the lab are analyzed to determine the correct diagnosis.
