Apple Series 4 watch has powerful ECG capabilities

Apple Watch Series 4 is capable of generating an ECG similar to a single-lead electrocardiogram. It’s a momentous achievement for a wearable device that can provide critical real-time data for doctors and peace of mind for you.

It can detect atrial fibrillation and detect when a person’s heart rate is too low. Apple got the Watch cleared by the FDA for direct-to-consumer purchase.

Electrodes built into the Digital Crown and the back crystal work together with the ECG app to read your heart’s electrical signals. Simply touch the Digital Crown to generate an ECG waveform in just 30 seconds. This data can indicate whether your heart rhythm shows signs of atrial fibrillation — a serious form of irregular heart rhythm — or sinus rhythm, which means your heart is beating in a normal pattern.

Apple Watch Series 4 can read and record heart beat impulses by connecting the circuit between your heart and both arms. The resulting ECG waveform, its classification, and any notes you’ve entered on related symptoms are automatically stored in the Health app on your iPhone. You can share them with your doctor and have a better-informed conversation about your health.

The Health app makes it easy to learn about your health and start reaching your goals. It consolidates health data from iPhone, Apple Watch, and third-party apps you already use, so you can view all your progress in one convenient place. And it recommends other helpful apps to round out your collection — making it simpler than ever to move your health forward.
