Irregular heart rate and atrial fibrillation can lead to cardiac arrest or stroke if not treated at the earliest. Fortunately, today some smartwatches and wearable devices come with clinically validated ECG sensors that can detect the early warning signs of a cardiac arrest, such as an irregular heartbeat and atrial fibrillation.

The advanced ECG smartwatches can take ECG or EKG readings within 30 seconds and alert you in case of atrial fibrillation. If you are not sure about your report, you may send your ECG or EKG report as a PDF file to your doctor for further analysis.

OUR TOP ECG SMARTWATCH RECOMMENDATIONS IN 2023

In addition to ECG, these devices can measure heart rate, blood pressure, blood oxygen level, skin temperature, and much more. This makes them an invaluable tool for doctors and health care professionals. Smartwatches can provide early warning signs of potential health problems by monitoring these vital signs.

According to a study, clinically validated ECG Smartwatches can facilitate the health promotion and early detection of cardiac arrest by detecting AF. But some people may find it hard to choose the best watch for themselves because too many health-tracking smartwatches are available.

Therefore, I have compiled a list of the best ECG Smartwatches in 2023 approved by the Food and Drug Administration (FDA). This means that the ECG-tracking smartwatches listed here have gone through clinical trials and have been proven to be accurate in detecting atrial fibrillation and other cardiac abnormalities.

This article aims to help you choose the most reliable ECG smartwatch out there in the market. We spent hours of time and effort developing this list of the best smartwatch with ECG approved by the FDA because we wanted to help people choose the right smartwatch.

Before we proceed further, let us have a quick look into what ECG is and how an EKG Smartwatch works. If you are in a hurry, you can directly jump to our list of handpicked ECG wearables here. 

What is ECG/EKG(Electrocardiogram)?

An electrocardiogram, also called an ECG or EKG, is a diagnostic test that measures the electrical activity of your heart. This test is used to detect a variety of cardiac conditions, including heart attacks.

The ECG procedure is simple and painless. It is usually done in a doctor’s office or hospital with the help of a 12-lead ECG machine to record the electrical activity of your heart from 12 different angles.

At the clinic, you will be asked to lie down on a table and place electrodes on your chest and limbs. These electrodes are connected to a 12-Lead ECG machine that records your heart’s electrical activity.

The test usually takes less than 5 minutes to complete. The ECG can diagnose heart diseases by identifying patterns(also called ECG variations) in the heart’s electrical activity.

What is an Atrial Fibrillation?

Atrial fibrillation is an irregular heartbeat that can lead to stroke, blood clots, or even heart failure if not treated at the earliest. CDC estimates that more than 12.1 million people (about twice the population of Arizona) in the United States may suffer from atrial fibrillation by 2030.

Age, high blood pressure, coronary artery diseases, lung diseases, etc., can lead to atrial fibrillation. By detecting the signs and symptoms at the earliest, we can prevent the progression and complications of the disease.

How does ECG work in a Smartwatch?

ECG tracking watches come with PPG sensors that sense the electrical activities of your heart. Then, the ECG app in the smartwatch analyzes the data for any irregular heartbeat or atrial fibrillation. If there are any warning signs, the app will alert you so you can get medical help right away.

Even though it does not give you much information like a 12-lead ECG, it is the most convenient way to track your heart health. You can wear it all the time on your wrist, and it does not have any wires or electrodes like a 12-lead ECG, making it very convenient to use. Advanced ECG watches such as Apple Watch Series 8, Ultra, Sense 2, and Samsung Galaxy Watch 5 alert you about irregular heartbeats.

If you get an irregular heartbeat notification, you can do an instant ECG for 30 seconds and get results immediately. Once the ECG or EKG is taken, the app assesses the rhythm and alerts you if there is an increased or decreased heart rate or atrial fibrillation.

After ECG, an ECG watch will give you any of the following results.

• Sinus Rhythm: An ECG report with sinus rhythm means that the ECG is normal. But in case of chest pain or any other associated symptoms, you must seek medical help immediately. 
• Atrial fibrillation: Atrial fibrillation in the ECG report means that the heart rhythm is not normal. It could be an early sign of a cardiac arrest or stroke. This severe medical condition needs immediate medical attention, even if you do not have chest pain or chest discomfort symptoms. 
• High or low heart rate: An ECG reading can also detect the heart rate. The ECG tracking feature in an Apple watch works only if your heart rate is between 50-120 or 50-150 beats/minute, depending on ECG Version 1 or 2.
• Inconclusive: Sometimes, an Apple watch can not classify your heart rate because of multiple reasons. The factors that lead to inconclusive ECG recording are a pacemaker’s presence, not wearing your watch correctly on the wrist, etc.
• Poor Recording: It is a new classification added to the Apple Watch ECG since the introduction of ECG Version 2 with Watch OS 7.2. A Poor ECG reading means that your Apple watch failed to classify ECG.

Advanced wireless wearable ECG devices such as Apple Watches have already saved many people by alerting them of an irregular heartbeat or atrial fibrillation. It is a life-saving feature that everyone should have on their smartwatch.

“Having an FDA Approved ECG Smartwatch is no longer a luxury; it is a necessity.”—

ECG Smartwatch Accuracy

If you are serious about buying a smartwatch that accurately tracks ECG, you should go for a smartwatch approved by the Food and Drug Administration (FDA). The FDA requires that ECG devices meet specific standards for accuracy and reliability. As a result, an ECG smartwatch that has been approved or validated by the FDA is the best option for those who are serious about tracking their heart health.

A smartwatch ECG accuracy study suggests that “The ECG feature also shows promise in AF detection and management and may enable users to take a more active role in their health care.” Plus, the AHA (American Heart Association) agrees that smartwatches with ECG can help doctors monitor patients’ heart health.

In this list, we have included many smartwatches with FDA-approved ECG features.

In the case of an accident, the Apple Watch Series 8 Car Crash detection features instantly call the local emergency department automatically, thanks to its advanced gyroscope and an accelerometer that helps the watch to detect if you’ve been in a car accident. The car crash features come in addition to fall detection, which also calls the Emergency Department in case of an unfortunate fall and you’re unresponsive for about a minute.

The new Apple Watch Series 8 is available in 41 and 45-mm case sizes, and both variants feature an Always-On Retina display with 1000 nits of brightness. It is available in aluminum and stainless steel casings with various color and band options. The watch’s price starts at $399 and is available to order from Apple.com and Amazon.

The Apple Watch Series 8 has 5 ATM water resistance, which means you can use this watch for swimming in shallow water for up to 50 meters. It also has a water lock and ejection mechanism that prevents water from entering the speaker. It also streams music via music streaming apps such as Apple Music, Deezer, etc., allowing you to download music into the watch for offline playback.

Unfortunately, the battery life of the Apple Watch Series 8 is still 18 hours, but it has a low-power mode that can extend battery life up to 30 hours by turning off features like an always-on display. The Series 8 supports fast charging. If you use a fast-charging USB-C Cable, it takes about 1.5 hours to reach 100%. This fast charging feature adds some relief to the short battery life of Apple Watches.

How to Take an ECG on Apple Watch?

Taking an ECG reading on an Apple Watch is very effortless. The procedure to take an ECG on every Apple watch is similar.

• Wear the watch on your wrist.
• Open the ECG app on your smartwatch.
• Once the app is open, just touch and hold the crown for 30 seconds(follow the countdown on the screen).

A detailed video shows how to take an ECG reading with Apple Watch.

Our Verdict

Apple Watch Series 8 is one of the best smartwatches with FDA Approved ECG in 2023. The addition of a new temperature sensor is an excellent addition for females. But I dont believe it is a deal breaker as it does not currently measure your skin temperature. Besides that, the Apple Watch Series 8 is just like the Series 7, and I do not recommend upgrading if you already own a Series 7.

2. Samsung Galaxy Watch 5 Pro: Best ECG Smartwatch for Samsung Phone

Like its predecessor, the Samsung Galaxy Watch 5 comes with an FDA-cleared ECG monitor. The Galaxy Watch 5, like other ECG watches, takes only 30 seconds to perform a full electrocardiogram. This ECG watch is easy to use and provides accurate readings that can be shared with your doctor.

In addition to ECG, the Galaxy Watch 5 has a 3-in-1 Bioactive sensor that measures your heart rate, blood oxygen level(SpO2), and body composition. The latest Galaxy Watch 5 has improved sleep monitoring features that can track your sleep more accurately than any previous models.

The Galaxy Watch 5 also included a temperature sensor that was not activated at the release. So we need to wait for a future software update to use it. Currently, the Fitbit Sense is the only other smartwatch with a built-in temperature sensor.

The Samsung Galaxy Watch 5 is available in three sizes, 40mm, and 44mm. The smaller model has a 1.19-inch AMOLED display, while the larger model has a 1.39-inch AMOLED display. Both models have Sapphire Crystal glass which is 60% stronger than the Galaxy Watch 4. Plus, the watch has 5 ATM water resistance and MIL-STD-810H approval, making it ideal for swimming and bathing.

The watch is powered by Wear OS and supports multiple Google Play Store Apps. The watch also has a built-in GPS, which allows you to accurately track your various outdoor activities such as running, cycling, hiking, etc.

• Expensive
• The temperature sensor is not yet activated

Our Verdict

The Samsung Galaxy Watch 5 is a good ECG Smartwatch with many health tracking features such as SpO2, Blood Pressure Monitoring, sleep tracking, body composition monitoring, etc. However, it has no new features that make it a must-buy if you already own the Galaxy Watch 4. The price of the Galaxy Watch 5 is also on the high side, but if you are looking for the best and latest ECG smartwatch, the Galaxy Watch 5 is worth considering.

3. Apple Watch Ultra: Best Rugged Smartwatch with ECG

The Apple Watch Ultra is the most rugged and expensive watch ever made by the company. The Ultra is packed with every feature of the Apple Watch Series 8, such as ECG, blood oxygen level monitoring, temperature monitoring, and many more. The Ultra will compete with high-end Garmin watches such as Fenix 7, Epix Gen 2, and Forerunner 955. However, we must wait and see how the Apple Watch Ultra fares in real-world usage.

The Electrocardiogram or ECG in this Apple Watch can detect irregular atrial fibrillation just like any other smartwatch. This Apple Watch also allows you to share your ECG report with your Doctor or family as a PDF. As mentioned, skin temperature monitoring is currently for females as it tracks their ovulation and menstrual cycles.

This advanced Apple Watch has a fall detection and car crash detection feature. It alerts Emergency Department with your location information as soon as it detects a fall or meets with a car accident. I pray to God that you never have to use this feature.

The Apple Watch Ultra is available only in 49mm size, which is very huge! If you have a small wrist, you may not feel comfortable with this watch. The Ultra has a Retina LTPO OLED 2000 display protected by a highly durable Sapphire crystal front and ceramic/sapphire crystal back. The watch is only available in a titanium frame and is water resistant up to 100 meters, just like many top-end Garmin watches out there.

The smart features of the Apple Watch Ultra include smartphone notifications, music storage, streaming features, fitness tracking, Apple Pay, and many more. The Ultra variant only comes with a GPS+LTE variant; thus, it allows you to make phone calls right from your wrist as there is an eSIM inside.

Apple has finally released a smartwatch with more than 18 hours of battery life and supports wireless charging. The battery can last even longer with Low Power Mode, which cuts down some features to save power. But is it enough to compete with Garmin watches that say battery life in weeks and months?

Pros

• Larger and brighter display
• Advanced health and safety features
• Irregular Heart rate alerts
• Detects Atrial Fibrillation
• Diving features
• 100 ATM water resistance

Cons

• Expensive
• Battery life still needs improvement

Our Verdict

The Apple Watch Ultra is not an ideal alternative to the Garmin GPS Sport watches. Obviously, it has more health-tracking features than any Garmin watches on the market today. However, when it comes to sport tracking features and battery life, the Apple Watch Ultra is still lagging behind. Plus, the bigger size and the high price tag of the Ultra will be a turn-off for many people.

4. Garmin Venu 2 Plus: Garmin ECG Smartwatch

If you are looking for a Garmin Smartwatch with ECG, the Garmin Venu 2 Plus is the only option available for you. Most of its rivals, such as Apple, Fitbit, and Samsung, introduced ECG features into their smartwatches more than a couple of years ago. Because of this reason, many Garmin watches users need to carry an additional ECG smartwatch to monitor their heart health. Finally, Garmin now has an ECG-enabled smartwatch with the Venu 2 Plus, and it has all the bells and whistles of an advanced health-monitoring smartwatch.

Like other smartwatches, this Garmin ECG takes only 30 sec to take an ECG reading. It also detects atrial fibrillation(AFib) and records the data in the Garmin Connect app. Venu 2 Plus also has a built-in heart rate monitor, sleep tracker, Pulse OX Sensor, stress tracker, and respiration rate monitor to help you closely monitor your wellness.

The Garmin Venu 2 Plus is an advanced health and fitness monitoring smartwatch packed with the latest features to help you closely monitor your health and fitness. Its advanced ECG feature and other tracking capabilities make it one of the best Garmin Smartwatches with ECG available.

5. Fitbit Sense 2: Best ECG Smartwatch for Android Users

Fitbit Sense 2 is the company’s latest launch, focusing on health and fitness tracking features. It comes with an ECG app, blood oxygen sensor, heart rate sensor, skin temperature sensor, irregular heart rythem, and many more.

The Sense 2 has an improved stress level monitoring sensor (e-EDA Sensor) for monitoring your stress in day-to-day life. It can alert you when there is an increased stress level and allows you to do breathing exercises to bring it down. Plus, it also has a dedicated Yoga App, which is also helpful in managing stress.

The Fitbit Sense 2 has a 1.58-inch AMOLED and is always on display with a 336 x 336 pixels resolution. It is available in 40mm size and made of a durable Aluminium casing and a silicone band. It is 5ATM water resistant and can track your swim workouts as well.

The Fitbit Sense 2 has a built-in GPS so that you do not need to carry your smartphone along with you. Plus, it has 40 pre-installed apps to monitor your activities, whereas Sense has only 20 apps. At the end of the day, you can see your performance in the form of colorful graphs and charts in the Fitbit App, which is very handy.

The smart features of the Fitbit Sense include smartphone alerts, NFC Payment, and streaming via apps such as Deezer, Spotify, and Pandora. Unfortunately, it does not have Bluetooth calling at launch, which was available in Sense. Like me, you will wonder why the Sense 2 does not have a Google Assistant or Google Maps at launch.

The Fitbit Sense 2 gives you almost 5-6 days of battery life with an AMOLED screen and all these features. However, if you use music and built-in GPS for longer, the battery will drain fast. The charging time for this watch is about 2 hours, similar to that of other Fitbit smartwatches and fitness trackers. I expected a fast charging feature in Sense 2, just like in the Galaxy Watch 5 and Apple Watch Series 7.

As expected, the Fitbit Sense 2 is an advanced health and fitness tracking smartwatch with many features, including an FDA-cleared ECG app, blood oxygen sensor, and skin temperature sensor. The watch also has a beautiful design that makes it suitable for any occasion. However, lacking an LTE variant and blood pressure monitoring features makes it less appealing to some users.

Pros

“Health by Fitbit,” Google itself calls the new watch’s fitness and health tracking features. The Google Pixel Watch has a built-in ECG (electrocardiogram) sensor that detects atrial fibrillation, just like any other ECG smartwatch mentioned here. Since Fitbit offers health tracking features, it is safe to say that the Google Pixel Watch will be an excellent choice for those looking for a smartwatch with good fitness and health tracking features.

Compared to Fitbit Sense 2, the Pixel watch does not have high and low heart rate notifications or irregular heart rhythm notifications. Plus, the stress and sleep tracking features are also not as advanced as the Fitbit sense 2. The skin temperature and SpO2 monitoring are the other important features missing on the Pixel watch.

The Google Pixel watch comes with a beautiful custom AMOLED color display with 1000 nits of brightness protected by the Corning® Gorilla® Glass 5. The case is made of Stainless Steel which is available in 41mm size only. The watch is also 5ATM + IP68 water-resistant, which means you can use this smartwatch in the shower or while swimming.

The Pixel watch is also offered in an LTE variety, allowing you to make phone calls, SMS, or use internet data without being connected to your smartphone. Since it uses eSIM, you can easily activate it via a phone call or by visiting a carrier store.

The battery life of the Pixel watch is 24 hours which is standard in many smartwatches with similar features, such as Samsung Galaxy Watch 4 or Apple Watch Series 8. With GPS, the battery can last only 12 hours, which is also not bad compared to Apple Watches.

Pros

• Attractive design and bright display
• FDA Approved ECG
• Music streaming support and music storage
• Highly accurate GPS
• LTE variant

Cons

• Expensive
• Limited health tracking features compared to Fitbit Sense 2
• Need Google Fit and Fitbit App

Our Verdict

Yes. Google Pixel is one of the best smartwatches for ECG monitoring, and it also has a beautiful design and a bright display. However, it lacks many health monitoring features such as SpO2, skin temperature monitoring, and EDA Sensor for advanced stress tracking. So, if you need a smartwatch with advanced health tracking features, then you should consider other smartwatches such as Samsung Galaxy Watch 5 or Fitbit Sense 2.

7. Apple Watch Series 7: Best Alternative to Apple Watch 8

Apple Watch Series 7 is one of my favorite smartwatches in 2022. In addition to ECG Monitor, the watch is packed with many health and fitness tracking features such as a Blood Oxygen Monitor, Activity Tracking, and more.

Fall detection is another excellent life-saving feature in Apple Watches. If you had a hard fall and did not respond for one minute, the Apple watch Series 4, and later models will automatically call the Emergency service with your location so they can reach you with the necessary help. Plus, the watch has an SOS feature that you can use to call the emergency service with a long side button press.

The Apple Watch 7 has an always-on retina display with 1000 nits max brightness. This ECG watch is available in two different sizes – 41mm and 45mm. You can choose from various case and band materials, such as Aluminum, Stainless Steel, or Titanium, based on your preference.

The Apple Watch 7 is also water-resistant up to 50 meters and tracks your swimming. However, it is not suitable for diving as forced water jets can break the water-resistant seals of the watch. If you need a diving smartwatch, consider the Apple Watch Ultra, designed for challenging outdoor activities like hiking, mountain biking, etc.

This Apple Watch Series 7 also stores and streams music, podcasts, and audiobooks through streaming apps such as Apple Music, Spotify, etc. You can also make phone calls and reply to messages right from your wrist. However, the battery life of the Apple Watch Series 7 is only 18 hours in normal usage, and the battery will drain even faster if you stream music or use GPS. Fortunately, it has a fast charging feature, and it takes only 90 minutes to charge the battery from 0-100%.

Pros

• It is tougher than the previous Apple Watches
• Clinically validated ECG

Our Verdict

If you are looking for a classy watch with health features such as ECG, SpO2, and activity tracking features, then you should buy the Withings ScanWatch. As it is a hybrid smartwatch, do not expect it to have all the features of a full-fledged smartwatch like the Apple Watch Series 8 or Galaxy Watch 5s. But it is still an excellent choice for anyone looking for an ECG tracking watch on a budget.

12. Withings ScanWatch Horizon: Best Hybrid Watch with ECG

The Withings ScanWatch Horizon is a smartwatch that looks great and has a lot of features to offer. At a glance, this watch looks like an expensive diver’s watch or Rolex! Its electrocardiogram (ECG) feature is clinically validated and approved by the FDA and can be used to detect irregular heartbeats such as Atrial Fibrillation.

In addition to ECG, this hybrid watch also tracks your heart rate, blood oxygen level (SpO2), steps taken, distance traveled, and calories burned. This ECG watch also has a sleep-tracking feature that can track your light, deep, and REM sleep.

This watch has a small monochrome LCD Display at the 12’O Clock position, which displays your current health and fitness metrics such as your heart rate, calories burned, etc. Plus, it also shows notifications from your smartphone on this watch.

The watch has a stainless-steel case and sapphire glass protection with a rotatable bezel, and it is also water-resistant up to 50 meters. The watch bands are interchangeable, and you can choose from a variety of colors and materials.

The battery life of this hybrid smartwatch is pretty good as well. You can expect to get about two weeks of battery life from a single charge with normal usage.

Unfortunately, this ECG watch does not have a built-in GPS, meaning you need to have your phone with you to track your runs or bike rides.

Pros

• Beautiful Classical design
• Longer battery life
• Sleep tracking features

Cons

• No built-in GPS
• Limited smart features

Our Verdict

The Withings ScanWatch Horizon is for those who do not like smartwatches but still want all the features that a smartwatch offers. Overall, the features of this watch are pretty much like that of the WithingsScan Watch, and the only difference is the design. But this watch has a premium design and feel to it. This watch is for you if you are looking for an ECG watch with longer battery life and sleep-tracking features!

13. AliveCor® KardiaMobile 6L EKG: Best Portable ECG Monitor

AliveCor® KardiaMobile 6L Mobile EKG is another FDA-approved wireless ECG monitor that assesses your heart rhythm and detects atrial fibrillation within 30 to one minute.  If you already own a smartwatch(without ECG) and do not want to invest more money on another smartwatch just for ECG, then you can consider buying a portable wireless ECG monitor such as AliveCor® KardiaMobile 6L Mobile EKG. 

If you feel, you can take an ECG with the device in 30 seconds and send it to the doctor through email. Also, sharing or storing ECG on the devices does not cost you any money.  Unlike other ECG devices discussed here, the AliveCor® KardiaMobile 6L Mobile EKG takes a 6L ECG and can give your doctor more information about your heart condition. 

In addition, if you subscribe to Kardia Premium, your ECG will be assessed by real human doctors for any complications. This service is optional; even without it, you can take and share ECG with your doctor for free. 

Besides atrial fibrillation, the AliveCor® KardiaMobile 6L Mobile EKG also detects other heart conditions such as bradycardia (slow heart rate) and tachycardia (abnormally increased heart rate), and sinus rhythm. 

Finally, AliveCor has collaborated with Mayoclinic to develop a technology to detect Long QT Syndrome (LQTS), a type of irregular heart rhythm. This condition is treatable but can lead to fainting or seizures. This may soon be introduced into AliveCor devices via KardiaBand.

Pros

• Small and easy to carry.
• FDA Approved Portable ECG device.
• 6-lead ECG monitoring.
• Compatible with Apple and iOS devices.
• Good battery life.

Cons

• Not as convenient as a smartwatch with ECG.
• Premium features require a monthly subscription.

Our Verdict

AliveCor® KardiaMobile 6L Mobile EKG is one of the best portable wireless ECG monitors with six lead ECGs. It is one of the best choices for people who already own a smartwatch and do not want to spend money on another advanced smartwatch.

However, in terms of convenience and portability, a smartwatch is far better than this device. 

ECG Smartwatch Related Questions (FAQ)

Here are some of the questions frequently asked by our readers about the best ECG watch. I hope this will help you.

12-Lead ECG vs. Single Lead ECG in Smartwatches

A 12-lead ECG assesses your heart from different angles and gives your doctor a wealth of information about your heart’s condition to diagnose various heart conditions, including cardiac arrest. That’s why 12-lead ECGs are considered the gold standard for diagnosing heart conditions.

While ECG Smartwatches cannot give you that much information, they cannot be used as medical equipment for diagnosis or treatment. However, it can detect Atrial Fibrillation (Afib) and abnormally low or higher heart rates. AFib can be deadly and lead to a heart attack or stroke if not treated.
