(FIT)-Module 5 Workshop 8: Device Cases-Poole Case 8 Question

Video Transcription

Video Summary

The likely scenario in this case is D: A 25-joule shock would likely defibrillate reliably. The electrogram indicates that the ICD detects ventricular fibrillation (VF), delivers a shock, and successfully terminates the arrhythmia, as suggested by the fast rhythm that appears to break with the shock. The high-voltage impedance of 53 ohms also suggests normal function of the ICD, improving the likelihood of effective defibrillation with 25 joules. The setup and delivered energy align with standard practices for defibrillation in similar clinical scenarios.
