What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting

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 tests whether an artificial intelligence program can use a simple, single-lead handheld ECG device to find people with undiagnosed atrial fibrillation (AF), a common heart rhythm problem. About 200 adults aged 50-90 will use a device at home and complete surveys. The goal is to see if this approach is accurate and acceptable for catching AF early.

The number the study aims to enrol. It can still change while the study runs.

Started

Expected to finish

Dec 2027

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.
