Workshop #7: Electrocardiographic/Electrophysiological Correlations, Atrial Fibrillation, Clinical Scenarios and Syndromes - Asirvatham

Video Transcription

Video Summary

In this video, Dr. Sam Asravatham, an electrophysiologist at Mayo Clinic, discusses several cases and scenarios related to cardiac arrhythmias. He presents intracardiac tracings and asks the viewer to identify the least likely diagnosis based on the tracing. He also explains the different circuits and pathways involved in atrial tachycardia, junctional tachycardia, and AV node re-entry. In another case, he shows an endocardial RV unipolar voltage map to determine the least likely diagnosis based on the voltage pattern. He then explains the importance of tissue contact and differentiates between right ventricular cardiomyopathy and epicardial fat. Additionally, he discusses how to localize the catheter position in the sinuses of Valsalva based on electrograms and fluoroscopy. Finally, he talks about differential pacing to diagnose fasciculoventricular pathways and the use of pacing maneuvers to determine exit and entrance block in patients with AFib undergoing pulmonary vein isolation.
