The study found that Apple Apple Watch has the highest ECG quality and the strongest readability.

CTOnews.com, Oct. 11, University Hospital in Basel, Switzerland recently tested five mainstream wearable devices, focusing on their ability to interpret ECG data, among which Apple Watch is the best.

CTOnews.com note: the standard ECG uses 12 electrode leads placed on a person's chest, arms and legs to monitor the electrical signals of the heart, while the mainstream wearable devices are mainly single-lead electrocardiograms.

The team invited 450 participants of varying professional or educational levels to evaluate single-lead electrocardiograms from mainstream wearable devices and found that Apple's Apple Watch ECG data were generally of higher quality and more readable.

The team tested five wearable devices: Apple Watch, Fitbit, Sense, KardiaMobile, Samsung Galaxy Watch and Withings ScanWatch.

The study compared the ECG recorded by the above wearable device with the 12-lead ECG records explained by two cardiologists, indicating that cardiologists can use single-lead ECG data to identify atrial fibrillation more accurately than residents or junior medical students.
