Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of the study is to confirm the Garmin ECG (electrocardiogram) software algorithm can detect and classify atrial fibrillation and normal sinus rhythm on single lead ECG data derived from a Garmin wrist-worn, consumer device. The study will also confirm the software's ability to create a Lead I ECG that is clinically equivalent to a reference device. The Garmin ECG software is not a diagnostic system and is intended for informational purposes only.
