(FIT)-Module 5 Workshop 8: Device Cases-Poole Case 2 Question

Video Transcription

Video Summary

A 66-year-old male with ischemic heart disease and a history of paroxysmal atrial fibrillation received an ICD shock for primary prevention. After experiencing shortness of breath, his device settings show a DDD pacing mode at 60 beats per minute, with a single tachycardia therapy zone at 207 beats per minute. Electrogram tracings suggest issues such as probable lead fracture, inappropriate therapy delivery for atrial fibrillation, appropriate ICD therapy for detected ventricular tachycardia, or ventricular over-sensing of atrial fibrillation. The case reviews these possibilities to determine the cause of the shock.
