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

Video Transcription

Video Summary

A 48-year-old with hypertrophic cardiomyopathy, having a dual-chamber Medtronic ICD implanted in 2014, experienced alerts during a remote device check. These alerts indicated an RV bipolar lead impedance issue and a warning about RV tip to coil lead impedance. Additional concerns about capture management and potential VF detection delay were noted. Examination of electrograms with arm motion and presenting rhythm data was necessary to determine the cause of the alerts. The choices to explain these findings included various types of lead fractures or a high-voltage lead fracture, each corresponding to the impedance warnings detected.
