The Apple Watch Series 9 comes with an array of features designed to monitor your health, with one of the standout features being the Electrocardiogram (ECG) function. This tool allows you to take an ECG using just your Apple Watch, helping you monitor your heart’s rhythm and detect irregularities such as atrial fibrillation (AFib). In this guide, we will explain how to enable and use the ECG function on the Apple Watch Series 9, providing easy-to-follow steps, troubleshooting tips, and additional insights about the feature.
Understanding the ECG Function on Apple Watch Series 9
What is an ECG?
An Electrocardiogram (ECG) is a test that measures the electrical activity of your heart. It tracks the rhythm and rate of your heartbeat, helping identify abnormalities that could indicate potential health issues, such as arrhythmias. The Apple Watch Series 9 allows you to take a single-lead ECG right from your wrist.
How Does the ECG Function Work?
The Apple Watch uses electrodes built into the back of the watch and in the Digital Crown (the round button on the side). When you touch the Digital Crown with your finger, it completes a circuit that allows the watch to record the electrical signals from your heart. These signals are analyzed to generate an ECG waveform.
Prerequisites to Use the ECG Function
Ensure Compatibility
To use the ECG feature on the Apple Watch Series 9, you must ensure that:
- You are using an Apple Watch Series 4 or later (Apple Watch Series 9 is compatible).
- Your iPhone is running iOS 15.0 or later.
- The ECG feature is available in your country or region (not all regions have access to ECG functionality due to local regulatory approvals).
Set Up Your Apple Watch and iPhone
Before enabling the ECG feature, make sure your Apple Watch Series 9 is properly paired with your iPhone. To do so:
- Open the Apple Watch app on your iPhone.
- Follow the on-screen instructions to pair the devices.

If the ECG function is available in your region, you’ll be able to use it.
Step 2: Set Up the ECG App
Once you confirm compatibility, set up the ECG app:
- On your Apple Watch, open the “ECG” app (it may be pre-installed or you may need to download it from the App Store).
- You will be prompted to read and accept the terms and conditions related to the use of ECG monitoring. Tap “Agree” to continue.
- You may be asked to set up or enable your health profile in the Health app on your iPhone. Follow the on-screen prompts to complete this setup.
Step 3: Enable ECG on the Apple Watch
To use the ECG feature, the function must be enabled:
- Open the “Watch” app on your iPhone.

How to Take an ECG on Apple Watch Series 9
Step 1: Prepare to Take an ECG
To take an ECG:
- Ensure your Apple Watch is comfortably positioned on your wrist.
- Sit still and relax your arm.
- Open the “ECG” app on your Apple Watch.
Step 2: Taking the ECG
To begin:
- On your Apple Watch, tap the “Start” button.
- Rest your finger lightly on the Digital Crown. Do not press it, as this can interfere with the reading.
- Keep your finger on the Crown for 30 seconds while the watch records your heart’s electrical signals.
Step 3: Review Your Results
Once the ECG recording is complete:
- The watch will display your results.
- You will see whether your heart’s rhythm is normal or if there are signs of AFib.
- If the results are abnormal, the watch may recommend seeking medical attention.
Interpreting Your ECG Results
Normal Rhythm
If your heart rhythm appears normal, the ECG app will display “Sinus Rhythm,” which means that your heart’s electrical activity is within the expected range.
Irregular Rhythm
If your heart shows signs of irregularity, such as AFib, the ECG app will display “AFib” and recommend you consult a healthcare professional for further analysis.
Troubleshooting ECG on Apple Watch Series 9
ECG Not Available in Your Region
If you find that the ECG function is not available:
- Check that your region supports the ECG feature by visiting Apple’s official website.
- Update your iPhone and Apple Watch to the latest versions of iOS and watchOS.
ECG App Not Working
If the ECG app is not working:
- Make sure both your Apple Watch and iPhone are updated to the latest software versions.
- Restart both devices and check if the ECG app becomes functional.
Poor ECG Reading
If the ECG results are inaccurate or unclear:
- Ensure the Apple Watch is properly placed on your wrist and that your finger is in full contact with the Digital Crown.
- Stay as still and relaxed as possible while recording the ECG.
