What series Apple Watch has EKG?

Apple Watch Series 4 and later, except SE, support ECG. Apple Watch Ultra models support it too, subject to Apple’s regional availability and setup requirements.

“EKG” and “ECG” refer to the same type of heart recording. Apple calls its watch feature the ECG app, so you may see either term while searching.

Model support does not guarantee that the app is available in every country or works with every older iPhone and software version. Check Apple’s current ECG app requirements before you buy or set up a watch.

Does Apple Watch SE have ECG?

No, Apple Watch SE models do not include ECG monitoring. If ECG is the deciding feature, compare a supported Series or Ultra watch instead of choosing an SE based on its release date or general health features.

Apple Watch SE can still provide other health and fitness features, but those do not substitute for recording an ECG. If you already own an SE, you’ll need a compatible ECG device or another supported watch to record one.

Which Apple Watch models have ECG monitoring?

The Series 4 introduced Apple’s ECG app, and later numbered Series models continued to support it. Apple Watch Ultra models also support ECG, while SE remains the exception among Apple’s main watch families.

A newer generation can still be subject to regional restrictions and setup requirements. Before buying used, ask for the exact model and check that its features match Apple’s support information for your country.

If you’re comparing a specific older model, see our guides to Apple Watch Series 5 ECG and Apple Watch Series 8 ECG.

What should you check before buying an Apple Watch for ECG?

Check the exact model, regional availability, and paired iPhone compatibility before choosing a watch. These details determine whether you can install and set up the ECG app.

1. Find the model name and generation in the watch’s settings or purchase details.
2. Confirm that it is a supported Series model or an Ultra, and not an SE.
3. Check Apple’s current country or region availability for the ECG app.
4. Confirm the paired iPhone and operating system meet Apple’s requirements.
5. Make sure you can set up the watch with your Apple account and region.

For a used watch, don’t rely only on its appearance or case size. Ask for its model identifier, because different generations can look similar.
