Background: Wearable health devices are becoming increasingly popular. The Apple Watch series 4 and 5 are the first wearable devices that allow consumers to generate electrocardiograms (ECGs) using the ECG app.
Obtaining an ECG using an Apple Watch is as easy as opening the ECG app and touching the digital crown with a finger. The watch then records 30 seconds of a “single-channel ECG similar to a lead I ECG” (1). An associated app (ECG app) in the iPhone (Apple) can do a rhythm analysis and classify the recording as sinus rhythm, bradycardia, tachycardia, or atrial fibrillation or as inconclusive.
