(FIT)-Module 4 Workshop 7: Electrocradiogrpahic and Electrophysiological Correlations, Atrial Fibrillation, Clinical Scenarios and Syndromes-Asirvatham Case 5 Question

Video Transcription

Video Summary

In this scenario, the patient has undergone a wide area circumferential ablation for persistent atrial fibrillation, with a circumferential mapping catheter in the right upper pulmonary vein. A key consideration is to determine whether there is an exit block, an entrance block, both, or if more information is required. The tracing involves an ECG, a circumferential mapping catheter in the right upper pulmonary vein, and an ablation catheter in the left atrium with coronary sinus catheter readings (CS1 and 2 being distal). To make a clinical decision, you need to analyze the tracing for any signs of block or gather additional information.
