(FIT)-Module 5 Workshop 9: Arrhythmia Case Studies (Putting It All Together for the Boards)-Ellenbogen Case 3 Answer

Video Transcription

Video Summary

The transcript discusses the differential diagnosis of inappropriate shocks from a subcutaneous ICD (sub-QICD), emphasizing T-wave over-sensing as the most common cause. Various scenarios of inappropriate shocks are described, such as T-wave over-sensing, air entrapment, and issues with set screws or seal plugs, along with possible solutions like changing the sensing vector or enabling filters. It also differentiates between appropriate device therapy and inappropriate shocks due to conditions like atrial fibrillation with rapid ventricular response. If preventive measures fail, replacing with transvenous systems might be needed.
