(FIT)-Module 3 Workshop 4: SVT and VT Invasive and Non-Invasive Correlation-Miles Case 7 Answer

Video Transcription

Video Summary

The video discusses adenosine-responsive accessory pathways, emphasizing their physiologic nature and differentiating them from typical accessory pathways. Adenosine can induce AV block, which is not common in usual pathways, but is useful for identifying accessory pathways. Although not rare, these pathways differ in response compared to fasciculoventricular connections, which have fixed pre-excitation. The importance of supplementing adenosine with physiologic maneuvers, like parahiss maneuvers, is highlighted for effectively distinguishing between AV node and accessory pathway conduction. The presentation concludes with the recommendation to use these approaches for accurate identification.
