The Apple Watch is more than just a fashionable accessory; it can also be an incredibly useful tool for monitoring your . With the introduction of the ECG app, you can now take electrocardiograms (ECGs) right from your wrist wherever you go. An ECG is a simple test that records the electrical activity of your heart over time and can help detect common heart disorders such as atrial fibrillation (AFib).

Fortunately, enabling the ECG app on your Apple Watch is a breeze. First, make sure your Apple Watch is running watchOS 5.1 or later and that it's a Series 4 or later model. Unfortunately, the Apple Watch SE does not currently support ECG. Once you've confirmed this, open the Settings app on your paired iPhone and select Language & Region. From there, select the region in which you live and save your changes.

Once you've done this, open up the Health app on your iPhone and select ‘Medical ID' from the tab bar at the bottom of the screen. Scroll down to find ‘Electrocardiogram (ECG)' and then select ‘Enable ECG' to turn on this feature for your Apple Watch. You should now be able to start taking ECGs directly from your wrist! Be sure to read all of Apple's safety information before using this feature to ensure that it works properly for you.

The ECG app is an exciting addition to Apple Watches that gives users another way to monitor their health while on the go. With just a few steps and some basic safety precautions, you can now start taking advantage of this powerful feature right away!

Is the ECG Feature on Apple Watch Free?

Yes, the ECG app and irregular heart rhythm notification feature are available today as part of a free update to watchOS 5.1.2, so it is completely free to use.

Accuracy of Apple Watch ECG Measurement

The Apple Watch Series 4 has demonstrated varying levels of accuracy for ECG detection. Its abnormal rhythm notification showed a sensitivity of 41%, while its single-lead ECG downloaded as a PDF had a sensitivity of 96%. However, this is still lower than the accuracy of telemetry, which is considered to be the gold standard for ECG detection. Therefore, it is important to note that the Apple Watch should not be used as a substitute for traditional medical diagnosis and treatment.


In conclusion, the Apple Watch is an incredibly powerful and versatile tool for tracking your health and well-being. The new ECG app and irregular heart rhythm notification feature make it even more valuable, allowing users to identify signs of AFib, the most common form of irregular rhythm. Additionally, with its many other features such as activity tracking and notifications for heart rate alerts, the Apple Watch is a great choice for those interested in keeping track of their health.
