(FIT)-Module 5 Workshop 9: Arrhythmia Case Studies (Putting It All Together for the Boards)-Ellenbogem Case 2 Answer

Video Transcription

Video Summary

The video discusses the optimal approach for cardiac resynchronization therapy (CRT) focusing on ensuring LV pre-excitation and wavefront fusion to enhance therapy effectiveness. The key is pacing the left ventricle (LV) first to achieve proper ventricular activation. It emphasizes that increasing output or shortening AV intervals isn't necessary as this only drains battery life. Proper CRT response involves observing changes in ECG waveforms, specifically the R wave, and optimizing conditions to ensure high CRT response. Low responders typically show minimal R wave development. Successful CRT requires careful patient selection, device programming, and managing coexisting arrhythmias.
