Session II: Invasive Diagnosis and Treatment-6154-Physiology and Catheter Ablation of AV Nodal Reentrant Tachycardia

Physiology and Catheter Ablation of AV Nodal Reentrant Tachycardia

Video Transcription

Video Summary

In this video, Professor Bill Miles discusses catheter ablation of atrioventricular (AV) nodal reentrant tachycardia. He explains that AV node reentry is a reentrant tachycardia involving two distinct pathways, the fast and slow AV nodal pathways. He describes the different forms of AV node reentry, including slow-fast, fast-slow, and slow-slow AV node reentry. He also discusses the diagnostic criteria for AV node reentry, including the location of the P wave and the use of vagal maneuvers. He explains the management options for AV node reentry, which may include catheter ablation or drug therapy. He emphasizes the importance of excluding other causes of tachycardia and using diagnostic maneuvers to confirm the diagnosis of AV node reentry. He also discusses the anatomy and pathophysiology of AV node reentry, including the role of the fast and slow pathways. He concludes by discussing the ablation procedure for AV node reentry and the potential risks and complications associated with the procedure.
