(FIT)-Module 5 Workshop 8: Device Cases-Ellenbogen Case 1 Question

Video Transcription

Video Summary

In the workshop, a 68-year-old man experienced a shock from his single-chamber ICD, implanted for syncope and ischemic cardiomyopathy. He experienced the shock shortly after passing an electrical power plant. The session reviews possible abnormalities based on clinic tracings, including elevated pacing impedance, shock timing, elevated pacing threshold, oversensing with short RR intervals, and decreased R-wave sensing amplitude. Participants are engaged in examining the tracings to determine the most likely cause of the shock incident, focusing on technical and environmental factors affecting the ICD performance.
