(FIT)-Module 4 Workshop 7: Electrocradiogrpahic and Electrophysiological Correlations, Atrial Fibrillation, Clinical Scenarios and Syndromes-Gerstenfeld Case 3 Question

Video Transcription

Video Summary

The transcript discusses a case of a 68-year-old woman undergoing catheter ablation for atrial fibrillation. During the procedure, wide area circumferential lesions are created around pulmonary veins followed by cardioversion. A circular catheter placed inside the left superior pulmonary vein is used to pace and map electrical activity, with reproducible findings. The task is to evaluate pacing results to determine the presence of entry and/or exit blocks. The options presented are: entry block only, exit block only, both entry and exit blocks, or neither. The video asks viewers to assess and decide which condition explains the tracing provided.
