Collaborator:

Information provided by:
Medtronic Cardiac Rhythm and Heart Failure
  Purpose
The purpose of this study is to test specific device programming in patients without a previous history of a life-threatening, abnormally fast heartbeat who are implanted with a Medtronic ICD (Implantable Cardioconverter Defibrillator) or ICD with CRT (Cardiac Resynchronozation Therapy) device. The information learned from this study could be used to guide physicians in future ICD or CRT device programming.

Condition Intervention
Tachycardia, Ventricular Implantable Cardioverter Defibrillator (ICD) Fibrillation, Ventricular Syncope Device: Implanted Device

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Prevention
Official Title: PREPARE - Primary Prevention Parameters Evaluation

Further study details as provided by Medtronic Cardiac Rhythm and Heart Failure:

Primary Outcome Measures:
  • Demonstrate that patients programmed using a prescribed set of parameters have a lower rate of cardiac syncope, symptoms of fast heart rate, VT/VF events and cardioversion or defibrillation shocks compared to patients programmed per physician discretion

Secondary Outcome Measures:
  • Evaluate the percentage of inappropriate VT/VF detections
  • characterize the true incidence of VT/VF detections
  • therapy efficacy
  • time to first inappropriate VT/VF detection
  • incidence of untreated but monitored VT
  • programming changes
  • deaths and cardiovascular adverse event

Estimated Enrollment: 700
Study Start Date: October 2003
Estimated Study Completion Date: May 2006
