An observational study in Atrial Fibrillation, sponsored by Seoul National University Hospital. Completed at 1 site in South Korea. Open to participants aged 19 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-08-20.
Sponsored by Seoul National University Hospital · Observational
This study aimed to detect and diagnose atrial fibrillation early by conducting a screening test for atrial fibrillation using a continuous electrocardiography monitoring device for those who have undergone a health screening examination.
Early detection through atrial fibrillation screening tests in high-risk patients with stroke is intended to prevent stroke by starting stroke prevention treatment early. It is intended to detect asymptomatic atrial fibrillation patients early through examination and ultimately improve the quality of life.

Evaluation of the convenience of wearing and using the Mobicare device
Questionnaire about convenience of wearing and using the Mobicare device 1. Did you feel uncomfortable going about your daily routine, and mainly when? 2. If you felt uncomfortable, what were your main concerns? 3. If your skin itches or breaks out in a rash during use, how long has it been since you've been wearing it? 4. How much discomfort did you experience due to foreign body sensation, skin problems, etc.? 5. Has your device ever been dropped while in use? If so, when did it happen? 6. Were there any challenges in reattaching the device, and if so, what were they? 7. How often have you taken your device off and put it back on? 8. How long do you think you can run the test without too much inconvenience?
Time frame: up to 1 month
