(FIT)-Module 5 Workshop 9: Arrhythmia Case Studies (Putting It All Together for the Boards)-Ellenbogen Case 1 Answer

Video Transcription

Video Summary

The slide illustrates the intermittent loss of both right ventricular (RV) and left ventricular (LV) capture during bi-ventricular pacing. Evidence of successful capture is indicated by the presence of T-waves, visible when either or both ventricles are captured. The RV tracing shows clear capture, confirmed by the accompanying T-wave, while loss of capture results in the absence of T-waves. The annotated beats demonstrate scenarios with both capture and non-capture in RV and LV, highlighting how T-waves serve as an indicator for ventricular depolarization and successful pacing.
