This study is looking at the Aveir VR Leadless Pacemaker System, a small device placed directly in the heart to help with irregular heartbeats (arrhythmia) or a slow heart rate (bradycardia). Researchers want to understand how well this pacemaker works and if it causes any problems compared to traditional pacemakers. They will look at how many people have complications within 30 days and how many are still alive after two years. This study uses existing health information from Medicare patients who have already received either the Aveir VR pacemaker or a standard single-chamber pacemaker. You would be included if you are a Medicare patient who has received one of these pacemakers.

Study design

This is an observational study, meaning researchers are looking at existing health data, not giving new treatments. It will include a large number of Medicare patients, with a planned enrollment of 8,744 people.

What's involved

No device intervention is required in this study, as it uses real-world data from patients who have already received a pacemaker.

Compensation

Not stated in the trial record.

Follow-up

The study will track participants for up to two years to see how many are still alive.
