The advice that I’m going to give here is based on my personal search for an ECG smartwatch for my requirements. I’ll give you all the features of the watch, but also the pros and cons of the smartwatch in the article.

Before I go any further, let’s look at what is an ECG and why you may need one.

My personal choice

My personal choice of the EKG watches, would be the Samsung Galaxy Watch 4. I find it to be particularly useful, in general, for health and fitness. It’s also compatible with both Android and IOS devices. It’s also hard to look past the fact that it’s FDA-approved.

I need to add here, though, that a smartwatch is not a replacement for hospital-grade medical equipment. They can, however, help you to identify any potential, or existing heart problems that you may have. 

What is an ECG?

ECG or electrocardiogram is a way of monitoring any heart problems that you may have. The ECG or EKG machine is commonly found in a doctors’ office or in ambulances. Your doctor will recommend an ECG if he feels that you’re having problems with your heart. 

The heart works by the atria and ventricles working together to pump blood through your heart. Electrical impulses from the brain travel to the SA node (sinoatrial), found in the right atrium. This causes the atria to contract, forcing blood into the ventricles. The rate and rhythm of the heart is set by the SA node. Each time the heart beats, some of the electrical impulses are sent to the skin. 

An ECG tracks and analyzes the electrical impulses at the skin level. Any difference in this electrical activity is can be a sign of potential cardiac problems. 

Heart problems may manifest themselves with symptoms such as:

  • Shortness of breath
  • Heart palpitations
  • Inability or reduction in the ability to exercise
  • Chest pain
  • Heart attack
  • Ventricular fibrillation

With the use of ECGs, the doctor can monitor any heart problems that you may have. He’ll be able to check your heart rhythm and check on any abnormalities that you may have with:

  • Blood flow
  • Abnormal calcium as well as potassium levels.
  • Cardiomyopathy (thickened walls of the heart)

How is an ECG done?

The electrocardiogram machine is a computer with a monitor which shows heart activity as waves. The output may also be shown as waves on paper coming out of a printer. The EKG machines have up to 12 electrodes that are attached to the patient. Each electrode comes is attached to the legs, chest, and arms of the patient with adhesive pads. The electrodes are connected to a monitor which records electrical signals which your heart produces when it beats. 

An EKG usually takes a few minutes to complete. Any movement, talking, or shivering will give a false result.

Types of ECG

There are different types of ECG. The main types include:

  • Ambulatory: which involves a small machine worn at the waist with electrodes attached.
  • Stress ECG: This ECG is done while the patient is exercising on either a stationary cycle or treadmill.
  • Resting: this is the one that’s usually done at the doctor’s office. This ECG is done while you’re lying done.

What is an ECG smartwatch?

The ECG smartwatch has the capabilities of an ECG monitor incorporated as part of its working. This enables you to monitor your own heart health anywhere you go. Feeling any heart palpations? Press down on the button you will activate the record for the ECG. Within less than a minute, you will be able to know your heart’s activity. Not only that, but you will be able to share it with your doctor from your watch or smartphone. 

So who needs an ECG smartwatch?

So you might be wondering, so why do I need an ECG smartwatch? If you’re a young person, you probably won’t find this smartwatch necessary. You will probably think it’s a waste of money or a new toy. On the other hand, if you’re over fifty, you will probably find it a necessary piece of equipment. Especially if you or somebody in your family has had heart issues in the past. 

You certainly couldn’t go wrong purchasing one of these smartwatches. Some symptoms of heart issues come and go at any time. You might be ok when you’re put on the ECG at the doctor’s office, but experience symptoms:  chest pains, shortness of breath, and heart palpitations when you’re mowing your lawn. An ECG smartwatch would come in handy since it’s always with the wearer.

What the ECG smartwatch measures

 The ECG smartwatch will still give you enough information to monitor what’s going on with your heart. 

An ECG smartwatch will give you the following information:

  1. Atrial fibrillation: Atrial fibrillations are irregular heartbeats. They are caused by the atria (upper regions) of the heart contracting randomly or at a speed at which the heart is unable to relax between contractions. If not treated in time, blood clots or heart failure will result.

The ECG smartwatch will warn when this event is happening so you can call a doctor immediately.

  1. Sinus rhythm: A normal sinus rhythm shows that the heart is beating rate of between 60 and 100 beats per minute. 
  2. Inconclusive: Contact your doctor immediately since this means the watch is not able to detect your heartbeat.

My pick of ECG Smartwatches

There are several great ECG smartwatch brands on the market. Here is my list of what I consider to be the best ECG smartwatches you can buy. 

#1 Apple Watch Series 5

I believe that the Apple Watch is one of the best ECG watches on the market today. This smartwatch can track and alert the wearer of:

  • Irregular heartbeats
  • Atrial fibrillation
  • Other irregular heart rhythms

Other features of this watch include:

  • An Always-on retina
  • An emergency SOS
  • Fall detection
  • Built-in compass
  • It’s also swim-proof up to 50 metres
  • Barometric altimeter
  • Ambient light sensor
  • 18-hour battery life
  • Sleep monitoring
  • A noise app that notifies you if sounds around you have reached a decibel level that affects your hearing.
  • A menstrual tracking app. This logs information about your menstrual cycles.
  • Can stream up to 60 million songs.
  • Can call or text without having your phone.

To take ECG using this watch, sit in a quiet place, similar to taking your blood pressure. Then open the ECG app. Keep your finger on the top for 30 seconds. A report will then be generated on the screen after another 30 seconds. You can also share your results with your doctor for analysis. 


  • ECG is FDA-approved
  • Durable design
  • Aluminum case
  • Music storage
  • Less expensive alternative to the Series 6


  • Expensive
  • No oxygen monitoring
  • Only works with other IOS devices

My verdict

Although the Apple Series 5 is one the top ECG watches, the problem that I have with it, is that it won’t work with Android smartphones. Also, if you want to track blood oxygen, you will have to step up to the Series 6. 

#2 Samsung Galaxy Watch 3

The Samsung Galaxy Watch 3 is my personal favorite ECG watch on this list. If you love a lot of features on your smartwatch or phone, like myself, this is definitely worth buying. Let me warn you that it won’t be cheap though. Price-wise, it will still be competitive with the Apple EKG smartwatches. It’s one of the most advanced Samsung Galaxy Watches to date. This stylish smartwatch will give you the following ECG results:

  • Sinus rhythm
  • Atrial fibrillation
  • Inconclusive

It will also have the following features:

  • Battery life of over a day on a single charge
  • Available in 2 sizes: 41 and 45mm
  • 1.4 inch oled (organic light emitting diode) display
  • Multiple colors available
  • A built-in running coach that can track 7 popular sporting activities
  • A sleep tracker that also monitors your stress levels
  • Fall detection and the ability to notify an emergency contact
  • Oxygen levels monitoring

  • Samsung Pay allows you the leave your wallet at home.
  • Several different styles to choose from.

To take your ECG with this watch, sit in a quiet place for between 5 and 10 minutes. Then open the Samsung Health Monitoring app. Touch the top right button and hold for 30 seconds or for the duration of the watch’s countdown. After 30 more seconds, the results of the ECG will then be displayed. 


  • Advanced sleep tracking
  • Physical rotating bezel
  • Built-in GPS
  • Blood oxygen tracking
  • ECG is FDA-approved
  • Android’s best wellness and health tracking smartwatch
  • Samsung Pay


  • Limited third party apps
  • Expensive

  • The ECG feature only works with compatible Galaxy smartphones

My verdict

With fall detection, blood pressure, blood oxygen level tracking, and a myriad of health tracking features, what more could one want from an EKG watch? It’s even compatible with some apple devices. Need I say more?

#3 Apple Watch Series 6

The Apple Watch Series 6 is an ECG watch that I’d highly recommend. It  has the following ECG features:

  • Atrial fibrillation
  • Sinus rhythm
  • Irregular heartbeat
  • Inconclusive

 Other features include:

  • Blood oxygen measurement.
  • Always-on retina display. 2.5 times brighter when the wrist is down
  • Workout measurement 
  • GPS
  • Sleep monitor
  • Waterproof up to 50 metres
  • Fall detection automatically calls your emergency department for help. 
  • Several different watch faces
  • Built-in music storage.
  • 18 hours of battery life.
  • Available in 2 sizes. 40 and 44 mm
  • 1.57 Oled display
  • Available in multiple colors
  • Silicone strap
  • Apple Pay
  • Siri

To take your ECG with the Series 6, sit in a quiet place for a few minutes. Rest your arms on a table or in your lap. Then open the ECG app. Keep your finger on the crown of the watch for 30 seconds. After 30 seconds, you will get your ECG results. You can then download the file with the results in PDF format and share it with your doctor.

Understanding the results:

  • Sinus rhythm: a result for sinus rhythm means that the heart is beating in a regular pattern. This is between 50 and 100 beats per minute (BPM). 
  • Atrial fibrillation: a result here means that the heart is beating in an abnormal pattern. If you have this classification without a diagnosis of Afib, you should have a talk with your doctor.
  • Low or high heart rate: a heart rate under 50 or over 120 – 150 bpm may affect the ECG’s ability to detect AFib. Some medications can cause a low heart rate. Also, elite athletes usually have a low heart rate. High heart rates can be caused by several different causes including, nervousness, AFib, exercise, stress, infection, and alcohol.


  • Always on display
  • Built-in GPS
  • Siri
  • Blood oxygen tracking
  • Altimeter
  • Highly developed activity and health tracking features


  • Only compatible with IOS
  • Expensive
  • Not so great battery life

My verdict

Not only does this smartwatch have blood oxygen tracking, but it has a wide variety of features as well. I believe that it would be money well spent if you were to buy the Series 6. Pity about it not working with Android smartphones though.

#4 Fitbit Sense

Another great ECG watch, in my opinion is the Fitbit Sense. This ECG Smartwatch can perform the following ECG duties:

  • Atrial fibrillation
  • Sinus rhythm
  • Inconclusive
  • Irregular heartbeat

Other features include:

  • Will track your electrodermal activity (skin temperature) to monitor the body’s reaction to stress.
  • Blood oxygen level

  • Battery can last more than 6 days. It will recharge in 12 minutes to give you a full day’s charge. 
  • Water-resistant to 50 metres
  • Stores and plays music
  • Female health tracking

The Fitbit has its ECG sensors behind the watch. So to take your ECG, wear it on your hand (not too tight or too loose). Sit quietly for a few minutes. Open the ECG app on the phone. Then hold the watch between your index finger and thumb. Wait 30 seconds. After a further 30 seconds, you will see the display on the screen. You can download and share your results in PDF format with your doctor. Past results are also available to download and view as well.


  • Always on display 
  • Battery life
  • Built-in-GPS

  • Alexa and Google Assistant
  • FDA-approved ECG function
  • Watch faces unlimited


  • No Spotify support
  • Small App store
  • Expensive
  • No blood pressure monitoring
  • ECG app presently not available in all countries

My verdict

I think this is one of the better EKG smartwatches here on this list. However if you would like blood pressure monitoring and emergency SOS, look elsewhere.

#5 Samsung Galaxy Watch Active 2

In my opinion, this is another great Samsung Galaxy ECG smartwatch. Besides ECG monitoring, it has the following features:

  • Built-in sleep tracker
  • Tracks your workouts
  • Can make or receive calls without a phone
  • Can detect falls
  • Oxygen level monitoring
  • Spotify playlist download and in addition to built-in music storage.

  • Blood oxygen tracking
  • Build-in GPS
  • Affordable
  • Minimalist design


  • Slow Bixby
  • Expensive
  • ECG only works with some Galaxy Smartphone models
  • Third party apps are limited

My verdict

While it may not be quite up to the Watch 3, it still has a lot of the features of its more expensive brother. As a matter of fact, it’s the cheapest Android EKG watch that you can buy.

#6 Apple Watch Series 4

This is another Apple Watch that I’d recommend if you’re looking for an Apple ECG watch. The Series 4 was released in 2018. This Apple watch comes with the following ECG features similar to other Apple watches already mentioned here. In addition to its ECG capabilities, it has the following features:

  • Fall detection and emergency SOS
  • 50 percent louder speakers
  • Workout detection
  • Activity tracker
  • Waterproof down to 50 metres
  • 18 hours of battery life
  • Durable design

Taking the ECG is the same here as with the previously mentioned Apple watches.


  • Built-in GPS
  • Built-in music storage
  • Heart-rate monitors are advanced
  • FDA-approved


  • Expensive
  • Only works with IOS

My verdict

This is the oldest of the Apple EKG smartwatches as it’s the first one ever built by Apple. However, no blood tracking and no blood pressure monitoring. Oh yes, and it’s not compatible with Android smartphone. 

#7 Withing Nokia ECG Smartwatch

The Withing Nokia ECG is the first analog watch with built-in ECG capabilities. It can instantly detect atrial fibrillation anywhere. It is also cheaper than most other ECG smartwatches. This smartwatch enables you to take your ECG by keeping your fingers on the watch for 30 seconds. This can be done anywhere and anytime. After this, you can share your results with your doctor. 

Cardiologists from well-known institutions assisted with the development of this watch.

 In addition to its ECG monitoring, it comes with the following features:

  • Water-resistant to 50 metres
  • Tracks more than 30 sports
  • Automatically monitors your sleep
  • Tracks daily activities
  • Battery lasts 25 plus days due to its hybrid nature.
  • Workout monitor


  • Comparably longer battery life
  • Ability to detect atrial fibrillation
  • Less expensive compared to other ECT smartwatches


  • Available only in European Union countries
  • Not FDA-approved
  • No touchscreen

My verdict

If you live in an EU country, this will be a great buy for you. It’s also more affordable than other smartwatches listed here. However, because it’s not FDA-approved, there could be some doubt about the accuracy of this smartwatch.

#8 Withings Move ECG

This is a hybrid ECG analog smartwatch. On the face, it looks like a regular analog watch but also has ECG monitoring capabilities similar to its brother. 

In addition to that, it has the following features:

  • Because of its analog face, it has a longer battery life than other regular ECG smartwatches. The battery can last up to 12 months without a charge.
  • Water-resistant up to 50 metres
  • Sleep tracking
  • GPS
  • Workout tracking

Taking your ECG with this watch is done in a similar way to the Withing Nokia. Simply press the button to activate the record. Then put your other hand on the ring electrode of the watch.

This is the only watch on this list that is not approved by the FDA. Therefore it’s not currently available in the USA.


  • Long battery life
  • Cheaper than most other ECG watches


  • Not FDA approved
  • Available on in EU countries

My verdict

Similar to other Withings Smartwatches on this list

#9 Withings Scanwatch Hybrid Smartwatch

This ECG hybrid also has an analog face, with a digital display for additional information, such as heart rate, step count, and other notifications. In addition to a medical-grade ECG, the Withings Scanwatch has the following features:

  • An oximeter provides a medical-grade oxygen saturation level on demand. 
  • Battery life of up to 30 days.
  • Sleep tracking
  • Respiratory monitoring
  • Step tracking to monitor the number of steps you take per day.
  • Cheaper than other ECG smartwatches

Place your finger on the bezel of the watch for half a minute. An ECG report will then be generated, which can be seen on your smartwatch.


  • Cheaper compared to other ECG smartwatches

My verdict

As with the other Withings smartwatches.

#10 Alevecor Kardiomobile 6L EKG

I’d recommend the Alevecor if you already have a smartwatch, but don’t want to invest in another one just for the EKG. This EKG device has a 6L EKG. This means more information for your doctor. Like an EKG smartwatch, you can share your results with your doctor by email. 

You can subscribe to Kardia Premium and have your results by doctors for any complications. Even without this optional service, though, you can still take your results and share it with your doctor for free. 

The Alevecor Kardiomobile will test for:

  • Atrial fibrillation
  • Sinus rhythm
  • Bradycardia (slow heart rate)
  • Tachycardia (unusually slow hear rate)


  • FDA-approved
  • Apple and IOS compatible
  • 6-lead ECG
  • Small and portable


  • Monthly subscription for premium features
  • Doesn’t have additional features of a smartwatch

My verdict

Buy it if you already have a smartwatch. 

If you’re looking for an ECG watch, any of these watches should satisfy your needs. However, if you’re an Apple user, the Apple Watch Series 4, 5, or 6 will do. The Series 6 will be the most advanced, while the Series 4 will be the cheapest of the group. 

If you’re an Android user, either the Samsung Galaxy Watch Active 2 or Galaxy Watch 3 will do. The 3, of course will be the more advanced of the 2. 

If you already have a smartwatch, the Alvecor will be a great add-on.
