Owners of some Samsung smartwatches can now take accurate ECG readings from the wrist – after the feature was launched in more counties worldwide.

Samsung’s latest smartwatches are capable of taking more accurate heart readings, with both the Galaxy Watch 3 and the Galaxy Watch Active 2 packing in ECG sensors just like the Apple Watch Series 6 and the Fitbit Sense watch.

While the sensors were in place on those watches when they first launched, Samsung has had to wait to get the necessary regulatory approval to turn it on for users.

It’s now live in Europe, as well as the US, South Korea and is rolling out across Japan, India and more countries. It’s not available in all locations, we’ll tell you which ones below.

ECG enables users to measure heart rhythms that could help detect the heart irregularity known as atrial fibrillation. However, it won’t detect other heart health issues like high blood pressure, congestive heart failure or blood clots.

If you want a deeper breakdown of what that is, we’ve got a pretty comprehensive atrial fibrillation and wearables guide you should give a read.

Which Samsung smartwatches can measure ECG?

It’s a good place to start. You need to have one of two Samsung Galaxy smartwatches to take ECG measurements. That’s either the Samsung Galaxy Watch 3 and the Galaxy Watch Active 2.

You won’t be able to do it on a Samsung Galaxy Watch Active, older Galaxy Watches and even Gear watches for a simple reason, They don’t have the ECG sensor built into their cases and this isn’t something you can simply add as a feature over a software update.

What else do you need?

This is really important. You have to have a Samsung smartphone to be able to use this feature. While Samsung’s smartwatches are compatible with Android phones and iPhones, you need to have access to software that’s only available through Samsung’s smartphones that are using Android 7.0 or above.

Does your country have ECG support?

Much like Apple and Fitbit, to turn that ECG feature on, Samsung will have needed to get the necessary regulatory approval in those countries to deem it suitable to take the kind of measurement that could reliably offer insights into your health.

In Samsung’s native Korea, it received clearance for its Health Monitor app, which unlocks the ECG feature, by South Korea’s Ministry of Food and Drug Safety (MFDS). It’s also been cleared by the FDA in the US.

In Europe, it’s also received the all-important CE-marking, which has made it available in 28 countries: Those countries are:

Austria, Belgium, Bulgaria, Croatia, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the UK.

There’s also plans to turn on the ECG feature in the United Arab Emirates, Indonesia and Chile.

Once you’ve established you have the right Samsung smartwatch, phone and you’re in a country that supports ECG, it’s time to get into how to get things set up.
