Outcome Measures

Primary Outcomes (1)

  • Primary Endpoint

    Event free survival of: 1. inappropriate ICD therapies (only stored tachycardias with proper stored EGM documentation are taken into account) AND 2. spontaneous, documented, sustained (\>30s) ventricular tachycardia, that was not treated by the ICD

    12 months

Secondary Outcomes (11)

  • Amount of patients with appropriate / inappropriate ICD therapies

    12 months

  • Prevalence of slow VT (<=187bpm) in patients with indication for primary prevention of SCD

    12 months

  • Number and cycle lengths of supraventricular / ventricular tachys

    12 months

  • Time to first appropriate / inappropriate ICD therapy

    12 months

  • Sensitivity for diagnosis of sustained VT

    12 months

  • +6 more secondary outcomes
