EP Fellows Curriculum: Retrograde Conduction-Retrograde Conduction

Video Transcription

Video Summary

In this video, the speaker discusses retrograde conduction during an electrophysiology study. Retrograde conduction refers to the activation of the atria in the opposite direction, from the ventricles to the atria. The speaker discusses different patterns of retrograde conduction and how to determine if it is present or absent. They also explain the importance of distinguishing between retrograde conduction and other atrial activation patterns, such as eccentric atrial activation or atrial tachycardia. Additionally, the speaker discusses the distinctions between conduction of the AV node versus an accessory pathway, and how to use extra stimuli to determine conduction patterns. They also highlight the importance of having a good hiss potential for accurate assessment of retrograde conduction. The speaker concludes by discussing the presence of retrograde conduction in different types of heart conditions, and emphasizes the need for further study to fully understand these patterns.
