Step 1: Launch the ECG app on Apple Watch Series 4 and hold your finger on the Digital Crown. This will complete the circuit and the electrical signals across their heart will be measured.

Step 2: After 30 seconds, the heart rhythm is classified as either AFib, sinus rhythm or inconclusive.

Apple, a well known strong advocate of the user privacy, has assured that all the data and the associated classifications including any noted symptoms will be stored securely in the Health app on iPhone. Users can share a PDF of the results with physicians.

Despite the aforementioned story, the ECG read-out and Irregular Rhythm Notification from the Watch Series 4 and later Apple watches, if the results come positive any heart ailment, you should never panic. Apple devices do diagnosis based on two electrodes (one on the crystal case below and another in the Digital Crown and sometimes it might show false positive for AFib condition.

In hospitals, doctors usually check with bigger instruments with 10 electrodes placed on different parts of the body to offer 12-lead reading, which will reveal the closest source of the cause.

So, if you get AFib or any other heart abnormal heart readings on the Apple Watch far too many times, it is in best interest you consult your doctor, but most importantly never feel anxiety and remain calm during the whole procedure. Even if you are diagnosed with any heart condition, you have to take proper medicine and make strict life choices in terms of routine exercise and develop healthy food habits.
