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

Video Transcription

Video Summary

In this case, a 68-year-old man with a biventricular ICD showing high LV pacing (99%) but no symptom improvement in heart failure is analyzed. The device interrogation reveals thresholds of LV 2 volts and RV 1 volt, both at 0.5 milliseconds. The potential fixes considered are: A) increasing LV pacing output, B) pacing the LV first, C) repositioning the LV lead, and D) echo-guided optimization of AV intervals. The key focus is finding the most effective way to optimize the device's configuration for improved patient outcomes.
