The ECG application will perform an electrocardiogram. Once launched, simply hold your finger on the Digital Crown to complete the circuit of electrical signals that will cross the heart. After 30 seconds, the heart rate is classified (atrial fibrillation, sinus rhythm or inconclusive) and then all is recorded in the health application of the iPhone.

Apple wants to allow its customers to share this document with their doctor to, once again, ensure optimal monitoring of health. In this respect, the Watch Series 4 has been certified by the Food and Drug Administration (FDA), which is the body responsible for granting marketing authorizations for drugs in the United States.
