The Apple Watch Series 4 is the first smartwatch ever that is able to perform an ECG reading, that you can instantly share with your doctor if needed! This is yet another potential life saving feature that has been added to Apple’s popular wrist-worn device. Let’s take a look at the requirements, the setup and how to actually take an ECG on the Apple Watch. But first of all, let’s define an electrocardiogram. The ECG is a test that analyzes the timing and strength of the electrical signals that cause the heart to beat. It’s a doctor’s main procedure of detecting heart problems.

The Apple Watch ECG feature has become available thanks to the release of watchOS 5.1.2. Because of hardware reasons, the ECG app is only available to the Apple Watch Series 4 owners. Due to legislation issues, in this initial stage, the feature is only available in United States, Puerto Rico, Guam and the U.S. Virgin Islands.

What Does The ECG App Do
This app uses the electrical heart sensor built-in the Apple Watch Series 4 and records the rhythm of your heartbeat. It detects your heart rate and checks the electrical pulses that make your heart beat. It compares the upper and lower chambers of your heart to see if they are in rhythm. This way it can detect the presence of atrial fibrillation, also known as AFib, a form of irregular rhythm.

How To Setup The ECG App
First of all make sure that your Apple Watch 4 is updated to watchOS 5.1.2 or later and that the paired iPhone is running iOS 12.1.1 or newer.

How To Take An ECG
With your Apple Watch on your wrist, you can take an ECG reading whenever you want. Your watchOS device is also able to notify you in case it detects irregular heart rhythm.
Important: Before starting make sure that the Apple Watch is properly strapped to your wrist!

How To Read The Result

– Sinus Rhythm: This result is positive. It means that your heart chambers are beating in rhythm. The heart is beating in an uniform patter between 50 and 100 BPM.
– Atrial Fibrillation: You will receive this result if your heart is beating in an irregular pattern between 50 and 120 BPM. AFib is the common form of serious arrhythmia. If you get an irregular heart rhythm result and you haven’t been diagnosed with AFib you should contact your doctor.
– Low or high heart rate: If your heart rate is below 50 BPM or above 120 BPM the ECG app can’t perform and accurate reading. If you’ve rested before the reading and get the low or high heart rate result you should contact your doctor because that’s not normal.
– Inconclusive: If you’re not resting your arms during the reading, or if the Apple Watch is too lose on your wrist you might get an inconclusive ECG result. In this case perform the proper adjustments and repeat the procedure.
