(FIT)-Module 5 Workshop 8: Device Cases-Poole Case 6 Answer

Video Transcription

Video Summary

The case discusses a ventricular pacesense lead fracture at the tip, identified despite the absence of typical large amplitude signals usually indicative of a fracture. The diagnosis was made based on the presence of far-field oversensing on the atrial channel and short interval signals linked to arm motion. Additional confirmation came from impedance abnormalities affecting both the tip-to-ring and tip-to-coil, indicating the fracture involves the tip. Despite not having classic large artifacts, the evidence supports the diagnosis of a ventricular pacesense lead fracture involving the tip electrode.
