(FIT)-Module 5 Workshop 8: Device Cases-Ellenbogen Case 3 Answer

Video Transcription

Video Summary

The video explains repetitive non-reentrant ventricular atrial synchrony (RNRVAS), not to be confused with pacemaker-mediated tachycardia. RNRVAS involves atrial pacing and retrograde atrial conduction, leading to rhythm issues. Retrograde P-waves fall in the post-ventricular atrial refractory period, resulting in non-capture, similar to AV desynchronization. Symptoms include fatigue and dizziness. RNRVAS can mimic pacemaker-mediated tachycardia in hemodynamics but is prevented with specific algorithms and adjustments like shortening AV delay. Highlighted as under-recognized, RNRVAS occurs when retrograde P-waves coincide with the P-bar, unlike typical tachycardia.
