Heart Failure, Congestive Clinical Trial
Official title:
OMNI Study--Assessing Therapies in Medtronic Pacemaker, Defibrillator, and Cardiac Resynchronization Therapy Devices.
The purpose of the OMNI study is to characterize therapy and diagnostic utilization in study
participants implanted with study devices and to describe Implantable Cardioverter
Defibrillator(ICD)therapy utilization for life threatening arrhythmias in primary and
secondary prevention study participants. This study will assess therapies in Medtronic
pacemaker, defibrillator, and cardiac resynchronization therapy devices.
The first therapy is for reducing unnecessary pacing in pacemaker patients. The second
therapy provides pacing therapy in an attempt to stop fast or life threatening ventricular
arrhythmias in lieu of delivering a defibrillation shock. The third therapy is a diagnostic
measurement of a patient's fluid status and provides the physician information on the
patient's heart failure status.
The study will also assess the time to a patient's first defibrillation shock and will
verify that the shock was for a fast or life threatening ventricular rhythm.
The OMNI results demonstrate the importance of Medtronic's ongoing efforts to increase adoption of evidence based shock-reduction programming strategies. Longer VF NID (number of intervals to detect in the VF zone) should be utilized with the Anti-tachycardia Pacing (ATP) During Charging Feature. ATP during Charging allows physicians to treat with ATP without delay to shock. Therefore, VF NID may be extended to allow episodes the chance to self-terminate immediately to shock by use of the ATP during the charging feature. ;
