Testing the Performance of Smartphones and Their Accessories in Detecting Irregularly Irregular Heart Rhythm
China209 participantsStarted 2025-08-27
Plain-language summary
The purpose of this 4-in-1 observational study is to test the performance of artificial intelligences (AIs) in distinguishing irregularly irregular heart rhythm called atrial fibrillation (AF) from normal heart rhythm using physiological signals collected by smartphones' built-in hardware and/or external accessories.
Participants will:
* Have their weight, height, resting heart rate and blood pressures measured
* Have 12-lead electrocardiogram (ECG) of their heart electrical activities recorded
* Have their heart sounds and 1-lead ECG recorded from their chest, and optical-based blood flow data (photoplethysmography or PPG) and 1-lead ECG recorded from their fingers using smartphones' built-in microphone, camera, and/or external accessories
* Optionally have their optical-based blood flow data recorded from their face using smartphones' built-in camera (remote PPG or rPPG).
The researchers will also create a database containing the physiological signals collected in this study along with the participants' medically relevant information to help train and test future AIs for medical applications.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Age: ≥22 years (adult)
* Patients who have one of the following:
* Permanent atrial fibrillation, or

* Confirmed 12-lead ECG diagnosis for persistent atrial fibrillation (\> 7 days) or sinus rhythm within 12 months at the time of their normal attendance at the hospital
Exclusion Criteria:
Any of the following:
* Implanted active medical devices in the torso, such as pacemakers and defibrillators
* Patients without atrial fibrillation who have another arrhythmia
* Completely missing one or more limbs, or missing any hand
* Disability in using their hands or arms

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
