There you go. Now, you’ve learned how to take ECG right from your wrist with your Apple Watch.

This feature is made possible with the help of electrodes that are built into the Digital Crown as well as the back of the Apple Watch. However, not all Apple Watch models pack these electrodes. To use the ECG feature, you’ll need an Apple Watch Series 4 or newer model with the exception of the recently released budget-oriented Apple Watch SE.

Depending on your heart rhythm, Apple Watch can show different results. If everything is normal, you should get the Sinus Rhythm result once the test is complete. The other possible results are Atrial Fibrillation, low heart rate, and high heart rate, each of which may require medical attention, or even urgent medical attention. It’s very important to keep in mind that Apple Watch cannot check for signs of a heart attack (yet anyway), so if you’re feeling anything heart-related that isn’t quite right, it’s better to be safe and visit an ER, doctor, or hospital.

If you wear the Apple Watch often and you have enabled irregular hearth rhythm notifications, then you may also get an alert if something isn’t right. If this happens, you should seek medical attention as well.

If you couldn’t find the ECG app and you were unable to install it, chances are, you’re living in a country that doesn’t support this feature. The ECG app is currently only available in 47 countries, but you can quickly check if your region is supported by going through this list on

We hope you were able to learn how to properly take advantage of the ECG feature on your new Apple Watch. What’s your take on this handy health feature and how often do you see yourself using it?
