To get ECG on a Samsung Galaxy Watch, pair a supported watch with a Samsung Galaxy phone running Android 12 or later, install and set up Samsung Health Monitor, and make sure ECG is available in your country or region. The feature is not available on every watch or in every market, even if the hardware is compatible.
Which Samsung watches and phones support ECG?
Samsung provides ECG through the Samsung Health Monitor app. Its compatibility guidance covers Galaxy Watch Active2, Galaxy Watch3, Galaxy Watch4, and later Galaxy Watch and Galaxy Watch Active models; Galaxy Fit is excluded. The instructions specify Active2 and Watch3 running supported Tizen software, and Watch4 or later running Wear OS 3.0 or later. You also need a Samsung Galaxy smartphone running Android 12 or later. See Samsung Health Monitor compatibility and safety information and the Samsung ECG instructions for use.
Why is ECG missing on my Galaxy Watch?
First check regional availability. ECG is a regulated medical-device feature, and Samsung says access varies by country or region. A compatible watch bought in a market where the service is not supported may not offer ECG. Samsung also notes that access may be restricted after a factory reset or app reinstall while traveling in a region where the service is unavailable. Check Samsung’s current country and region availability list before changing settings or buying a device; Samsung groups supported markets by device.
If your region is supported, check the remaining requirements in this order:

How to record an ECG on your Samsung watch
- Wear the watch snugly on your wrist and sit with your forearms resting comfortably on a table.
- Start the ECG recording in Samsung Health Monitor on the watch.
- For 30 seconds, lightly touch the watch’s top/Home key with a fingertip from your opposite hand. Keep still and do not talk. Do not press the key; pressing it stops the recording.
- When the reading ends, review the result on the watch. If you have symptoms, you can add them to the report, then tap Done.
- With the watch paired to the phone over Bluetooth, review the synchronized report in Samsung Health Monitor on the phone. The phone app can create a PDF report.
Samsung’s ECG measurement instructions and instructions for use describe the recording procedure.
Can I use ECG without a Samsung phone?
No—not through Samsung Health Monitor’s supported setup. Samsung requires a compatible Galaxy Watch paired with a Samsung Galaxy smartphone running Android 12 or later. A compatible watch alone, or a non-Samsung Android phone, does not meet the stated phone requirement.

What the ECG result can—and cannot—tell you
Samsung describes the feature this way: “The Samsung Health Monitor ECG app detects ECG signals (similar to a Lead I ECG) with the help of your Galaxy Watch’s ECG sensor and determines whether atrial fibrillation or normal sinus rhythm is present.” It records and classifies a signal; it is not a diagnosis or a substitute for professional medical care.
Samsung says the app is not intended for people under 22 or people with known arrhythmias other than atrial fibrillation. Its guidance also says not to use the app with an implanted pacemaker, implanted cardiac defibrillator, or another implanted electronic device. Do not make clinical decisions based on a watch result without consulting a qualified healthcare professional. If you have concerning symptoms, seek urgent medical care rather than relying on a watch reading.
