Smartwatches in 2025 now offer medical-grade ECG monitoring for real-time heart health tracking.
Leading brands like Apple, Samsung, and Fitbit are integrating ECG features into stylish and user-friendly wearables.
ECG-enabled smartwatches help detect irregular heart rhythms and support proactive cardiovascular care.
Smartwatches can do a lot more now than just count steps and tell time. In 2025, lots of them can even check your heart with something called an ECG (electrocardiogram).
This helps spot weird heartbeats, which could be a sign of serious stuff like atrial fibrillation. Since everyone’s getting more into health stuff, these ECG smartwatches are getting popular because they could save your life and they're easy to use.
This article points out some of the best smartwatches you can buy in 2025 that have ECG, and we're checking out how well they work, how accurate they are, and if they're worth the money.
ECG monitoring on a smartwatch records your heart’s electrical signals. This helps find any weird heartbeat patterns. It’s easy to use anytime, so you can keep an eye on your heart without going to the doctor. It’s really helpful for watching out for atrial fibrillation, which is common but often missed.
The Apple Watch Series 9 is still one of the best for health tech. Its ECG app is fast, gives you clear results, and is approved by the FDA. Just hold your finger on the Digital Crown to take an ECG, and you’ll have results in under 30 seconds. You can keep the data safe and even send it to your doctor.

The Huawei Watch D is made for people who want all the details about their health. It also counts steps, tracks stress, and has workout modes.
Picking the right smartwatch depends on what you need. Like if it works with your phone, how much money you want to spend, what you think looks good, and if you want other health features. Some watches work best with certain phones (like Apple or Samsung), but others like Fitbit and Withings work with more types of phones.
How long the battery lasts, how easy it is to use, and how clear the screen is also matters. Some people might want a normal-looking watch, while others want a bright screen and fun features.
Smartwatches that check your heart with ECG aren’t just a cool thing to have. They’re becoming important for keeping an eye on your heart. You can find anything you want in 2025, from fancy models to cheaper ones, that give you reliable ECG tracking and other ways to stay well.
