Outcome Measures

Primary Outcomes (1)

  • Number of Patients With Inappropriate Ventricular Tachycardia (VT)/Ventricular Fibrillation (VF) Therapy (Shock or Antitachycardia Pacing [ATP]) After the Pre-Discharge Visit

    An inappropriate therapy is defined as a VT/VF therapy, either shock or antitachycardia pacing (ATP), delivered for a supraventricular tachycardia (SVT). All events for which a VT/VF therapy was delivered and a stored electrogram exists were reviewed by an independent adjudication committee to determine the appropriateness of device rhythm classification and subsequent therapy delivery.

    From date of pre-discharge until a minimum of 12 months follow-up until study closure

Secondary Outcomes (3)

  • Time to First Inappropriate Shock Using VITALITY and Selected Medtronic Implantable Cardioverter Defibrillator (ICDs)

    Time of event

  • Positive Predictive Value (PPV) of Ventricular Tachycardia/Fibrillation (VT/VF) Discrimination Algorithms Found in VITALITY 2 and Medtronic Implantable Cardioverter Defibrillators (ICDs)

    Time of event

  • Time to First Inappropriate Therapy for Which the Discrimination Algorithm Found in VITALITY 2 and Medtronic Implantable Cardioverter Defibrillator (ICDs) Inappropriately Classified the Episode

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients who meet current indications for an ICD
  • Patients who sign and date a Patient Informed Consent form prior to the implant visit
  • Patients who remain in the clinical care of the enrolling physician in approved centers
  • Patients who are able to tolerate ICD programming as specifically prescribed in the study protocol

You may not qualify if:

  • Patients who are in third degree heart block
  • Patients whose life expectancy is less than 12 months
  • Patients who have other cardiac surgeries or procedures planned but not yet performed during the duration of the study
  • Patients who are currently enrolled in another investigational study or registry that would directly impact the treatment or outcome of the current study
  • Patients who are younger than 18 years of age
  • Patients who are mentally incompetent and cannot sign a Patient Informed Consent form or comply with the study
  • Patients who are pregnant or plan to become pregnant during the study
