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.

Apple Watch 7 is a new addition to the Apple Watch product line. The latest flagship watch comes with revolutionary sensors that take your ECG anytime. 

The watch is tested several times, and every time it shows very precise results. Once you have taken ECG on your Apple Watch 7, it shows the sign of atrial fibrillation or sinus rhythm. 

How ECG app Works On Apple Watch 7?

There are built-in Electrodes in the Digital crown that takes the readings. When you touch your finger with Digital Crown, it reads your heart’s electrical signals. To generate a complete waveform, you have to touch the digital crown for 15 seconds. 

And after taking ECG, your Apple Watch 7 shows you the following results, which you must know to maintain your 

normal heart rhythm.

Sinus Rhythm: If your ECG results show a Sinus rhythm, it means your heartbeat is in a uniform pattern between 50 and 100 BPM. But in case of any fatigue on your chest, you should consult with your doctor.   

Atrial Fibrillation: This indicates an irregular heartbeat pattern. Atrial fibrillation is a serious form of arrhythmia, and if you notice AFib, you must talk to your doctor.

Low or high heart rate: In Apple Watch 7 ECG app also detects your heart rate. But this will only track your heart rate if it’s between 50-120 BPM.   

Inconclusive: Sometimes, your Apple Watch shows inconclusive results for several reasons. Few physiological conditions prevent some users from creating enough signals to produce good results. Similarly, an ECG app will not work correctly if you have a pacemaker. 

How you can get the best ECG results on Apple Watch 7:

  •  Reset your arm on any table and try to relax your whole body.
  •  Make sure the band should be tight enough to take signals.
  •  Make sure your Apple watch and wrist are dry. 
  • Don’t keep any electronics around you during ECG. 

Apple Watch 7 gives more precise and fast ECG readings than Apple Watch 6. Here you will get ECG readings in just 15 seconds. 

What Apple Watch 7 ECG App Doesn’t Offer

Although you can use Watch 7 to take ECG or EKG readings, you can’t use it for serious medical purposes. 

Apple Watch 7 can’t detect your heart rate or any chest pain. In case of these situations, you should consult with your doctor immediately. Similarly, the ECG app can’t detect any stroke or blood clot.

How Can You Set Up Heart Rate Notification On Your Apple Watch?

Apple watches allow you to keep track of your heart health. That’s why it added health notification features. When every heartbeat remains above or below your selected beats, your watch will notify you about this fluctuation. 

You can set this notification for your Apple Watch app. 

First, open the Apple Watch app, then next tab my watch and tab Heart. Select heart rate and then BPM.

 

Other Features:

Apart from ECG or EKG, Apple Watch 7 is loaded with many health-tracking features. The more helpful feature spotted here is blood oxygen saturation monitoring that tells about the overall wellness of your health. 

Similarly, the watch also includes stress management, a valuable feature for every person. You will also get breathing exercises that help you to reduce your stress. Plus, some audio and video-guided meditation allow you to stay focused and active.

Like predecessors, you will get sleep tracking, calories tracking, and downs of workouts to monitor your outdoor activities effectively.

Overall Verdict:

Undoubtedly, Apple Watch 7 is an outstanding device, especially if you’re looking for the best ECG smartwatch. It tracks every activity in detail so you can keep an eye on your weak point. 

The battery life is disappointing and similar to the Apple Watch 6. You can use your watch for 18 – 22 hours, and then you have to put it on charge. But luckily, Apple added magnetic fast charging support that boosted the charging speed.

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.

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. 

Accuracy Of ECG Smartwatch

If you are going to buy an ECG smartwatch, you should go with that smartwatch approved by the FDA (Food and Drug Administration).

ECG smartwatches that are FDA-approved are clinically validated to be accurate. FDA tests the device profoundly and thoroughly for its performance and accuracy. This makes it difficult to get FDA approval.

The ECG smartwatches are very convenient because these smartwatches allow you to take multiple ECGs directly from your wrist. These smartwatches are helpful because they keep you alert and save you from significant complications.

Pros And Cons Of ECG Smartwatches

According to the Harvard medical school data, over 160 million people will soon use wearable tech like smartwatches to track their health and fitness.

These smartwatches can be a big boon for heart patients as few of them also monitor ECG. But at the same time, it is stated that 30% of wearable devices give inaccurate results. 

Similarly, Dr. Ivor Benjamin, the president of the AHF, said that some people report symptoms that are not found in them. This is because of using inaccurate wearables to evaluate your health. Also, AHF doesn’t endorse any ECG smartwatch. 

According to sciencedirect there are a few pros and cons of ECG smartwatches include;

Pros:

  • Patient empowerment by having direct access to personalized health measures.
  • Evaluation of patients with palpitations.
  • Monitoring of atrial fibrillation in a high-risk population.
  • Coaching on AF burden and recurrence rate.

Cons:

  • Price, accessibility
  • Lack of continuous monitoring
  • Privacy and security issues of personal data generate by consumer wearables
  • Don’t detect heart rate
  • False or inaccurate results may lead to stress

Conclusion

There is no doubt that the number of deaths because of sudden heart attacks increases day by day. It is essential to keep track of your heart rate, and overall health is essential. Therefore we provided you with information about the popular choices for the best smartwatch with ECG.

Apple Watch Series 6 is the most popular smartwatch with ECG functionality. It can alert you immediately for any abnormality in your heart rate.

I hope we were able to guide you thoroughly and provide answers to your questions. I hope you had a great time reading this article, and it will be great if you choose a smartwatch from our list.

  3. Thanks for your text. I would also like to say that the health insurance agent also works for the benefit of the coordinators of your group insurance plan. The health insurance professional is given a listing of benefits looked for by an individual or a group coordinator. What any broker will is seek out individuals or perhaps coordinators that best match up those needs. Then he provides his recommendations and if all sides agree, this broker formulates a binding agreement between the two parties.
