What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study looks at how well the Micra AV2 pacemaker can detect atrial fibrillation (AFib) in people who already have a history of paroxysmal AFib. Researchers will monitor 50 patients using the pacemaker's signals and a special Holter monitor. The goal is to understand how often AFib occurs and how the device tracks the heart's natural rhythm.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this study could help doctors better understand how the Micra AV2 pacemaker detects hidden atrial fibrillation, potentially improving monitoring and treatment for patients.
What could go wrong
This is a small, observational study (50 people) that does not test a new treatment or safety. It only gathers data, so it cannot directly improve patient outcomes.
