We updated this article on November 3, 2022. And added some new smartwatches with ECG features, including Apple Watch Series 8, Galaxy Watch 5, and Fitbit Sense 2. So you will keep updated gadgets.

Why Choose FDA Approved ECG Smartwatch:

Note: You should only choose smartwatches approved by the Food and Drug Administration. 

The FDA evaluates health risks and determines the benefits of medical devices. A medical device must pass FDA standards to get formal approval. Likewise, different smartwatches brands like Apple, Samsung, and Fitbit have to submit the results of their clinical tests to get support. 

Getting approval from FDA is not an easy job; depending upon the medical product quality and risks FDA puts them in different categories. Here you can check the difference between FDA-approved and clear and registered medical devices.

Similarly, manufacturers must submit the 510(k) form for some medical devices to demonstrate that the device is safe and works effectively. It’s a long process that takes 3 months, and after that, a device is regarded as a medical device.

Things To Consider Before Buying A Best Smartwatch With ECG

No matter which ECG smartwatch you will buy, you must consider these factors to buy the perfect one.

1- Accuracy

To get the perfect ECG smartwatch, first of all, you have to consider the accuracy of that smartwatch. If that watch gives accurate results of the ECG app, then you are ready to go for that watch.

2- SpO2 Feature

The best smartwatch with ECG is incomplete without the SpO2 feature. By using this feature, you can find out how well your heart pumps oxygen throughout your body.

People with conditions that affect blood oxygen levels may use it to monitor their health, especially if they are in the hospital.

2- FDA Approved

The next thing that you have to check in the watch that you are going to buy is whether it is FDA approved or not. If yes, then you can go for that watch.

An FDA-approved product means that the FDA has decided that the product’s benefits outweigh the known risks. The manufacturer must submit a pre-market approval application and results of clinical testing.

3- PPG  Sensor

For monitoring heart rate, photoplethysmography (PPG) is an uncomplicated and inexpensive optical measurement method. 

PPG measures the volumetric variations of blood circulation by using a light source and a photodetector at the skin’s surface.

The PPG sensor is the plus point for the best ECG smartwatches.

4- Temperature Sensor

Signals from this sensor are used to measure temperature. When it detects a temperature change, the sensor produces an electrical voltage or resistance.

If the watch contains this feature, it is the plus point for that watch, and you are pretty good to go for it.


What is ECG/EKG(Electrocardiogram)?

During an electrocardiogram, your heart’s electrical activity is recorded. Heart disease is quickly detected and monitored with this painless test.

ECG is one of the fastest and the simplest tests and is done by placing electrodes at certain essential spots of the body, including your chest, legs, and arms.

Using the lead wires, the electrodes are connected to an ECG machine. This process provides you with your heart’s electrical activity, which is then measured, analyzed, and printed out.

Remember, during an ECG, no electricity is sent into your body. Electrical impulses help keep blood flowing effectively in the heart by coordinating contractions of different parts.

An ECG test provides a lot of essential information to the doctor. This information includes:

  • Fast heart rate (tachycardia)
  • Slow heart rate (bradycardia)
  • Heart rhythm
  • Heart-rate irregularities
  • Heart attack
  • Heart block
  • Atrial fibrillation
  • Ventricular fibrillation

Until modern wireless ECG devices became available, it was impossible to record your ECG at home. However, a smartwatch can alert users of abnormal heart rhythms (cardiac arrhythmias), but it cannot recognize a heart attack. 

This allows you to get medical attention as soon as possible before any further complications arise.

What Is An Atrial Fibrillation?

ecg smartwatches

Atrial fibrillation (AFib) is an irregular and sometimes very rapid heart rhythm (arrhythmia) that may lead to blood clots in the heart. In addition to stroke and heart failure, A-fib increases the risk of heart-related complications.

The symptoms of Atrial Fibrillation are fatigue, chest pain, shortness of breath, etc., and are caused by Lung diseases, Sleep apnea, high blood pressure, heart attack, etc.

What Is A Ventricular Fibrillation?

Fibrillation of the ventricles is a type of abnormal heart rhythm (arrhythmia). In ventricular fibrillation, the lower heart chambers (ventricles) twitch (quiver) uselessly due to disorganized heart signals. 

Consequently, the heart does not pump blood to the rest of the body. The most common symptom of ventricular fibrillation is collapse and loss of consciousness.

How ECG Smartwatches Work?

Most smartwatches come with Photoplethysmography (PPG) sensors, which measure the changes in blood volume passing through the wrist. Similarly, smartwatches take an ECG reading, and the algorithms process extracted data and show you ECG reports.

According to ScienceDirect, “The”Peak” to ”peak” interval pulsation can be used in algorithms to detect atrial fibrillation (AF). Different smartwatch brands have different AF detection algorithms, which can be affected by wrist position, motion, ectopic beats, etc.

Taking an ECG on smartwatches is entirely different from taking ECG on professional devices. For example, in the case of the latest Apple watches, you have to hold your finger on its digital crown for 30 seconds. 

Similarly, in Galaxy watches, you have to hold your finger on the back button for 30 seconds, and it will generate results. And in the case of Fitbit, you have first to open the ECG app, and it will ask you to place your finger on the corner of Fitbit. 

Should You Buy An ECG Smartwatch?

Before choosing an ECG smartwatch, the question arises why I would buy an ECG watch? These watches are not helpful; some people take ECGs for fun and then forget these features. Users between 20 and 30 years don’t need an ECG watch; they should watch a sport to track their activities. 

But on the other hand, people over 50 should buy an ECG smartwatch because they need to regularly take care of their health. And also, if you are a person with heart problems, then such smartwatches are valuable for you. 

Apart from each ECG, users can also measure their other health factors like blood pressure, SpO2, sleep, calories burned, temperature, etc. 

There is a deep sea of smartwatches in the market, so it isn’t easy to trust one single brand. If you are infested with ECG watches, you should look for brands like Apple, Samsung, or Fitbit. These brands have a high reputation and trust rates to rely on their smartwatches. 

Can ECG Watches Save Your Life?

Although ECG watches can’t work like professional medical instruments, still these gadgets are helpful to measure your ECG at home.

FDA approves the latest Apple and Samsung watches for Atrial Fibrillation tests. The watches effectively recognize arrhythmia (irregular heartbeat), so individuals can take precautions to avoid major future problems. 

Fitbit’s new Sense is currently improving its ECG app, and the FDA does not yet approve it. But in a few months, it will be approved and show the same results as Samsung, and Apple Watches do. 

Both Apple Watch and Fitbit Use the same optical photoplethysmography (PPG sensor) to detect heart rate. But like Apple Watch, Fitbit won’t be continually monitoring for signs of Atrial Fibrillation. 

Apple watches also offer heart rate alters that notify you about your irregular heart rates or BPM. With such notification, you can check your wellness and caution to avoid complex issues.  

ECG watches are not made to detect heart rate or any issues; you should consult with your doctor if you feel such problems.
