Outcome
- Type
- PRIMARY
- Title
- Number of Patients With Inappropriate Ventricular Tachycardia (VT)/Ventricular Fibrillation (VF) Therapy (Shock or Antitachycardia Pacing [ATP]) After the Pre-Discharge Visit
- Description
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.
- Time frame
- From date of pre-discharge until a minimum of 12 months follow-up until study closure
