Information provided by:
Medtronic Cardiac Rhythm and Heart Failure
  Purpose
The purpose of this study is to look at the heart rate and rhythm information collected daily in Medtronic implantable pulse generators (IPG), implantable cardioverter defibrillators (ICD) and cardiac resynchronization therapy (CRT) devices. The study will gather this information from many patients to see if heart rate or rhythm data can predict the risk of a patient having a medical condition such as stroke.

Condition Intervention
Atrial Fibrillation Stroke Heart Failure Device: Diagnostic

Study Type: Observational
