Before I’ll cover the 14 best ECG smartwatches, however, I’ll cover a buyer’s guide to getting you to think about the most important factors before purchasing an ECG smartwatch which are all factors I’ve thought about thoroughly before selecting the 14 best ECG smartwatches.

But first, I’ll start with a comparison table of the 5 most outstanding ECG smartwatches in this article, and right after that, I’ll fully explain the answers to essential questions regarding ECG (like, for example, what an ECG is, and what ECG smartwatches are).

Comparison Table Of The 5 Most Outstanding ECG Smartwatches Of This Article

What is an Electrocardiogram (ECG)?

An electrocardiogram is a medical test that is often used in medical clinics or hospitals to check a person’s heart rhythm.

These tests are done by attaching sensors on a person’s skin which then can detect electrical signals that are produced by their heart each time it beats.

The results of this test are then examined by a specialized doctor who can see whether the result is unusual or not.

This is also why electrocardiograms are often requested by a doctor whenever he/she suspects that you have a problem with your heart.

What Is An Atrial Fibrillation (AFib)?

An Atrial Fibrillation is an often very rapid and irregular heart rhythm that can result in blood clots forming in the heart.

Also, it is known that Atrial Fibrillation increases the risk of getting a stroke, or heart failure, and it can also lead to many other heart-related problems.

Atrial Fibrillation presents itself by the heart’s upper chambers beating very irregularly and out of sync with the lower chambers that are present in the heart.

Atrial Fibrillation, however, often occurs without any symptoms and, therefore, is often not caught before a stroke or another heart-related problem occurs.

There are, however, also warning signs out there that could give away a potential Atrial Fibrillation episode like a fast pounding heartbeat, weakness, or shortness of breath.

How is an ECG normally done?

Doctors in medical clinics or hospitals often perform the test, and the test starts by sticking sensors on the skin of the person that needs the test.

These sticking sensors are often put on the chest, arms, and legs of the person which are then connected to an ECG recording machine.

The ECG recording machine then makes a reading of the heart rate, and can then provide the doctor with information on the heart health of the person.

How often should ECG readings be taken?

For people that have a heart condition that could lead to fatal ends, it is important to at least have a yearly ECG to make sure that the heart rate of the person remains in check.

It is also important to have a yearly ECG if you are a person that is at a higher risk of getting a heart attack.

And if the person with a heart condition or with a higher risk of getting a heart attack is feeling fine even then an ECG should be taken.

A yearly ECG for people with these conditions is, however, a general rule to follow but it can, of course, also be that your doctor or general practitioner has other ideas and you should, of course, always follow the guidelines of your doctor or general practitioner.

What different types of ECGs exist?

Three different types of ECGs exist that are often used:

• An ECG, while the person is resting, is most often done to get a good idea of the current heart condition of a person.
• A Stress ECG is another test that is often done to test how the heart of a person is performing whilst the body is performing an exercise on, for example, a cycling machine, or treadmill.
• An Ambulatory ECG is a test that is often done to test how the heart of a person is performing during normal day-to-day activities.

What are ECG smartwatches?

ECG smartwatches are smartwatches that can take an ECG reading whilst being on the wrist of the wearer.

The ECG smartwatch can take an ECG by completing an electrical course throughout the body of the wearer.

Whilst the smartwatch is situated on the wrist of the wearer then the smartwatch has two ways of performing an ECG.

The first way is through the heart rate monitor that is present on the back of the smartwatch that is pressed against the wrist.

And the second is when the wearer touches the crown of the watch for a certain amount of time with a finger from the opposite hand.

What can ECG smartwatches do?

An ECG smartwatch is capable of measuring whether the person in question has Atrial Fibrillation or whether the person has just a normal heart rate.

An ECG smartwatch is capable of doing these tests multiple times a day which enables you to keep a close eye on your heart health.

An ECG that is performed at a medical clinic or the hospital can detect Arrhythmias which often present themselves through a heart that is beating too slow, too quickly, or irregularly.

Besides Arrhythmias, it can also detect Coronary Heart Disease which occurs when the blood supply to the heart is interrupted by a build-up of fatty substances, and it can detect whether the person in question is having a heart attack or not.

An ECG smartwatch is unable to detect all the just mentioned health-related issues apart from Atrial Fibrillation.

The reason why ECG smartwatches are so popular is that Atrial Fibrillation is a major problem within, for example, the US as it, generally, affects 1% of the total population.

How do ECG smartwatches work?

ECG smartwatches, generally, have a built-in sensor that is capable of doing on-the-spot readings of your heart rate.

These ECG smartwatches, generally, also come with a built-in app that can be used to start the ECG reading.

Before clicking the button to start a reading it is, generally, required for the watch wearer to place his/her finger on the case or the crown of the smartwatch during the whole reading to ensure that the sensor will give the wearer an accurate result.

You can check out the video below if you want to learn more about how ECG smartwatches work through video content.

What measurements does the ECG smartwatch make?

The ECG smartwatch is capable of measuring your heart rate, and heart rate rhythm which in turn is then either classified as a sinus rhythm which is a normal reading or as Atrial Fibrillation which is an abnormal reading.

How can ECG smartwatches save your life?

ECG smartwatches are capable of detecting Atrial Fibrillation which is an abnormal heart rhythm that can lead to a stroke or other health-related problems.

An ECG smartwatch can take an accurate ECG reading if the smartwatch in question is FDA Approved, and once the measurement has been taken then the result can be directly shared with your doctor who can then take appropriate action promptly.

How to take the best ECG readings with your ECG smartwatch?

There are various things that you can do before doing an ECG reading to have a better chance of the reading giving a correct result:

• The first thing that you can do is to relax your whole body.
• The second thing that you can do is to make sure that both the watch and your wrist where the smartwatch is located, are dry.
• The third thing that you can do is to make sure that there aren’t any other electronics around, apart from your smartwatch, that might be able to affect the reading.
• The fourth thing that you can do is to make sure that the band of the smartwatch is attached tight enough to your wrist to take any signals.

Are ECG smartwatches accurate?

ECG smartwatches that have been FDA Approved are very accurate when it comes to their ECG readings because they’ve been heavily tested.

ECG smartwatches that instead come from brands that have not been FDA Approved can come with inaccurate readings because they haven’t been heavily tested on their accuracy.

Most ECG smartwatches that come from the brands: Apple, Samsung, Fitbit, and Withings are FDA Approved and will, therefore, be accurate in their ECG readings.

Who needs an ECG smartwatch?

An ECG smartwatch can be helpful for every single person to have because Atrial Fibrillation doesn’t always cause symptoms, and can, therefore, develop unnoticed until a stroke or other heart-related health issue occurs.

Also, for people that already have heart disease or that are at a higher risk of getting heart disease, it is essential to get an ECG smartwatch to be able to monitor their heart health often which also enables them to quickly share their results with their general practitioner.

What are the pros and cons of an ECG smartwatch?

Various pros and cons come with having an ECG smartwatch.

Pros

• That you can take an ECG reading in about 30 seconds.
• That you can take an ECG reading whenever you like and how much you’d like.
• That you can directly share the ECG reading with your general practitioner which is very handy because your GP can then take appropriate action quite fast whenever the reading turns out to be bad.
• ECG smartwatches from very reliable brands are FDA Approved which means that their ECG readings are tested for appropriate accuracy.

Cons

• ECG smartwatches are unable to replace medical-grade equipment as ECG smartwatches are built solely for detecting Atrial Fibrillation.
• ECG smartwatches are unable to detect a heart attack.
• Whenever the ECG smartwatch wearer also has a pacemaker then a reading can give inaccurate results.
• ECG smartwatches from very reliable companies can be quite expensive.

Buyer’s Guide

Durability

It is heavily important that your investment in an ECG smartwatch will be an investment that will last for a long time.

Therefore, it is essential to select an ECG smartwatch that is highly durable, so that it doesn’t break or stop working if you, for example, accidentally drop it.

Also, every smartwatch will over time get some bruises along the way, and to make sure that these bruises will not have any negative effect on the performance of the smartwatch, it is essential to choose an ECG smartwatch from a reputable brand that will be covered next.

Reputable Brand

There are a plethora of smartwatch brands out there that sell smartwatches with an ECG feature but not all smartwatch brands will give you the value that you deserve to get when you have invested in one.

Examples of smartwatch brands that are very trustworthy when it comes to delivering quality are Apple, Samsung, Fitbit, Garmin, Fossil, Withings, and Huawei.

This is also the reason why, in this article, you’ll only find ECG smartwatches that come from the brands: Apple, Samsung, Fitbit, and Withings because smartwatches from these brands will give you the value you deserve for your every penny even though they are, generally, not the cheapest options out there.

If I needed to choose an ECG smartwatch then I would for sure pick a watch from the brands Apple or Samsung because the effort that’s put into the smartwatches from these two brands is just insanely good.

Battery Life

Buying an ECG smartwatch with decent battery life is another essential feature that should be present in your ECG smartwatch, simply because doing accurate ECG readings multiple times throughout your day will drain the battery faster than you think.

Therefore, it is once again essential to buy the ECG smartwatch from a reputable brand, for example, Apple, Samsung, Fitbit, or Withings.

FDA Approved

An FDA Approved ECG smartwatch is a smartwatch that has been heavily tested to make sure that the ECG readings that the smartwatch can make are accurate each time.

It is, of course, very important that the ECG smartwatch that you decide to buy is FDA approved because if you, for example, have heart disease then it is essential that every ECG reading is accurate so that you can take appropriate action immediately if a reading turns out to be worrisome.

The most reputable smartwatch brands that come with FDA Approved ECG smartwatches are Apple, Samsung, Fitbit, and Withings.

5. Fitbit Sense – * Best Fitbit Smartwatch With ECG *

The Fitbit Sense is the best Fitbit smartwatch that is out there with an ECG feature which is a great option for people that love the Fitbit brand, and also need an ECG feature in their smartwatch.

Besides its ECG feature, the Fitbit Sense has a lot more to offer which I’ll also cover after I’ve shared with you how you can take an ECG reading on the Fitbit Sense, and also after I’ve shared which outputs you can expect from its ECG feature.

How can you take an ECG reading with the Fitbit Sense?

Taking an ECG reading with the Fitbit Sense smartwatch is quite simple.

The following steps will guide you through how to do it:

1. The Fitbit Sense comes with a built-in ECG app that you first should open up.
2. Once the app is opened then you’ll first have to set everything up before you can do an ECG (check the video below which will guide you through how to exactly set everything up).
3. Once everything is set up on your connected smartphone then it is time to put the watch on your wrist.
4. Open the ECG app up again and move through the instructions given on your smartwatch’s screen.
5. Once the smartwatch asks you to do so then put your index finger and thumb on the metal corners of the watch, and hold them there for the duration of the reading (a timer will count down).
6. Once the timer is done then you’ll immediately see the results on your watch’s screen.

If you’d, however, rather watch a video on how to take an ECG reading with the Fitbit Sense, then you can check out the video below.

What outputs can the ECG feature of the Fitbit Sense give you?

The results that you can expect to see after you’ve taken an ECG reading are a sinus rhythm, an Atrial Fibrillation, or an inconclusive reading.

The inconclusive reading can occur due to a too high heart rate, a too low heart rate, or it can occur because the watch was unable to make a correct reading.

Heart Rate Too High

A too high heart rate may be present in you because you have engaged in very recent exercise, because of stress or nervousness, because of consuming alcohol before the reading, because of dehydration, because of an infection, or it might be a sign of Atrial Fibrillation or another arrhythmia.

Heart Rate Too Low

A too low heart rate on the other hand may be present in you because of taking certain medications, because of having excellent aerobic fitness, or because of another arrhythmia.

Unable to make a good reading

Whenever the watch was unable to make a good reading then this can be the result of moving too much during the reading, not resting your hands on a table during the reading, or because of another arrhythmia.

What you need to do to get a good reading

If the watch was unable to make a good reading then you should do the following things to have a higher chance of getting a good reading:

• Double-check if the Fitbit Sense is properly fitted on your wrist (it should feel comfortably fitted and not too secure or too loose). Also, make sure that you wear the watch about the width of your finger above your wrist bone.
• Make sure that there aren’t any other electronics around when you’re doing the ECG reading.
• Make sure that the Fitbit Sense, the wrist where the watch is on, and your hands are clean and dry because, for example, water or sweat can interfere with the reading if present.
• Make sure that you keep both your index finger and thumb on both corners of the watch for the duration of the required time to do a reading (30 seconds).
• Make sure that the Fitbit Sense is present on the correct wrist that you selected before starting your ECG reading (either left or right).
• Make sure that the arm where the watch is fitted, is resting on a table during the reading.
• Also, make sure that you’re sitting down and that you relax during the ECG reading.
