NCT02314598

Brief Summary

This is a prospective, non-randomized, multicenter, post market release study which will collect electrograms (EGMs) from patients at risk of a suspected insulation failure to the high voltage portion of the defibrillator lead and will evaluate the electrogram signals.

    24 hours

Secondary Outcomes (2)

  • Proportion of Patients With Abnormal Electrograms and Lead Failure

    1 month

  • Additional Abnormal Electrogram Characteristics

    1 month

Limitations and Caveats

41 out of the 46 enrolled subjects completed a Holter recording with at least 12 hours of telemetry, but none of them reached any study endpoint. Therefore enrollment and study were closed and foreseen analyses could have not been performed
