(FIT)-Module 5 Workshop 9: Arrhythmia Case Studies (Putting It All Together for the Boards)-Ellenbogen Case 8 Answer

Video Transcription

Video Summary

The transcript discusses dual AV nodal non-reentrant tachycardia (DAVNNT), characterized by a single P wave conducting through both fast and slow pathways, resulting in two-for-one conduction patterns seen in QRS complexes. It differentiates DAVNNT from AV nodal reentrant tachycardia (AVNRT), highlighting that DAVNNT typically shows a significant disparity in AH intervals and lacks VA conduction. It is often misdiagnosed and can be a rare cause of tachycardia-induced cardiomyopathy. The suggested site for ablation in the EP-LAB is the slow pathway.
