Detecting Atrial Fibrillation in Patients After Stroke
Official title: Develop and Validate Machine-Learning Algorithm to Detect Atrial Fibrillation With Wearable Devices
Run by Emory University · NCT05795842 · Data updated 2026-11-12
This study is testing a new smartwatch tool to see if it can help find atrial fibrillation in people who have had a stroke, to reduce their risk of having another one.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 55 and older who have had an ischemic stroke of uncertain cause and are receiving follow-up care at the Emory Stroke Clinic.
✕Probably not a fit
Patients younger than 55 or those without a need for extended cardiac monitoring may not benefit from this study.

What this trial studies
This study aims to validate a machine-learning software for long-term monitoring and detection of atrial fibrillation (AF) using biometric data collected from consumer smart devices like smartwatches. It will enroll 500 subjects who have experienced an ischemic stroke of uncertain cause and are being followed at the Emory Stroke Center. Participants will undergo standard extended ECG monitoring alongside the use of a wearable wristband. The goal is to improve the diagnosis of AF, which is often asymptomatic but can significantly increase the risk of subsequent strokes.
Why it matters
Potential benefit: If successful, this study could lead to earlier detection and treatment of atrial fibrillation, reducing the risk of future strokes in patients.
How similar studies have gone: Other studies have shown promise in using consumer technology for health monitoring, but this specific approach is novel.
