(FIT)-Module 5 Workshop 8: Device Cases-Ellenbogen Case 4 Answer

Video Transcription

Video Summary

The discussion focuses on managing T-wave oversensing in patients with implantable cardioverter-defibrillators (ICDs). Firstly, non-invasive solutions like reprogramming, adjusting sensitivity, and verifying ventricular fibrillation (VF) sensing should be attempted. Lead revision or repositioning might be necessary if T-waves are disproportionately larger than R-waves. Switching to an integrated bipolar sensing configuration could also be beneficial. It's crucial to address T-wave oversensing promptly to prevent inappropriate shocks in patients, particularly during post-pacing pauses or spontaneous rhythms. While smaller R-waves complicate matters, larger R-waves provide more programming options, reducing the need for lead revision.
