Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Summary
Brief summary
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.
