A Clinical Research Study for Adults Who Could Be At Increased Risk for Stroke
Associated With Undiagnosed Atrial Fibrillation or Atrial Flutter, Two Common Heart Rhythm Abnormalities
This clinical research study is to determine if monitoring your heart rhythm to find undiagnosed Atrial Fibrillation or Atrial Flutter reduces the risk of stroke compared to usual care without monitoring.
About the Study
This study may be a good fit for you if:
- You are 70 years or over
- Have not been previously diagnosed with Atrial Fibrillation or Atrial Flutter
- You do not have an implanted cardiac device and
- You have health insurance by Medicare Part A & Part B Medicare (Fee-for-service)


The study requires only one visit, either in person at your doctor’s office or remotely at your home. At the visit, we will answer any questions you have about the study. If you decide to participate, you will sign an informed consent form that gives you information about the study and how we will use your personal health information. After you sign the consent form you will be randomly (like flipping a coin) to wear a Zio®XT heart rhythm monitor or continue usual care without a monitor. If you are assigned to wear the monitor, it will be applied in your doctor’s office if the visit is in person or at home, if you do not want to go to the office. You will remove the monitor after wearing for 14 days and return it in a postage-paid box that comes with monitor. We will compensate you for participating in the study. By participating in this study you can learn more about your health and possibly help others in the future.
