If you are looking for smartwatches that can detect AFIB, this guide is for you.

Atrial fibrillation or AFIB is a common heart problem which affects millions of people worldwide including 6 million Americans. It’s more common in elder people but it can also develop in young people.

It’s a serious condition which can cause serious heart issues but luckily, there are smartwatches which can detect it at early stages and In this guide, I’ll tell you about them.

In this WearToTrack guide, I’ll focus on following topics.

  • What is Atrial Fibrillation?
  • Common Symptoms of Atrial Fibrillation
  • Different Stages of Atrial Fibrillation
  • How ECG can detect Atrial Fibrillation?
  • Accuracy of Smartwatches when it comes to AFIB detection
  • List of smartwatches that can detect Atrial Fibrillation
  • And many more!

So, without any further ado, let’s get started.

Here is an article on my website that you must read, its about 11 Best Thinnest Smartwatches | You Won’t Feel It On Your Hand.

What is AFIB?

Let’s start with the very definition of AFIB. Atrial fibrillation or AFIB is a common but lethal heart problem that occurs due to the irregular rhythm of your heart.

In simple words, AFIB occurs when the upper chambers of your heart go out of sync with the lower chambers of your heart.

Once your heart develops this condition, your heart is exposed to various deadly complications such as Stroke, Heart failure, and Cognitive Decline.

What Are The Symptoms of AFIB?

Now the problem with AFIB is that it’s asymptomatic, especially in the early stages, which means that if a person develops this condition, there are chances that you won’t be able to detect it unless you do the ECG test or suffer a stroke. However, these are some of the symptoms which you may experience if you develop AFIB.

  • Chest Pain
  • Dizziness
  • Fatigue
  • Lightheadedness
  • Weakness
  • Shortness of Breath

How Common is AFIB?

According to CDC, AFIB is one of the most common types of heart problems, and by 2030, the number of AFIB patients will cross 12.1 million in the US alone, and this number will be way higher if we combine the cases from around the world. Also, it’s responsible for around 20 to 30% of heart strokes.

What Are The Different Stages Of AFIB?

When it comes to AFIB, cardiologists have classified AFIB into three types.

  • Paroxysmal AFIB – It’s the sudden episode of AFIB where your heart experience AFIB, but it’s not lethal, and it can stop on its own without any medical help. As it comes for a short period, it isn’t easy to detect.
  • Persistent AFIB –  It’s the second stage of AFIB where you can experience it for over a week, and it’s also possible that it becomes permanent.
  • Permanent AFIB – it’s the 3rd and last stage of AFIB which is considered the most severe stage. In this stage, the AFIB continues to get worse, and it’s difficult for a heart to restore its natural rhythm.

What is an ECG, and How Can It Detect AFIB?

What is an ECG, and how can it detect AFIB

When it comes to detection of AFIB, you can only do it with an ECG test. ECG or Electrocardiogram is a test that basically measures the electrical activity of your heart.

It basically records your heart movement, and if it detects any irregular rhythm, it shows in the test, which you can use to diagnose the condition.

In smartwatches, you get the advanced algorithm that analyses the ECG test for you, and if it detects AFIB, it will notify you so that you can get professional help on time.

How Accurate is AFIB Detection on Smartwatches?

Now the next question is: how accurate is AFIB detection on Smartwatches? And What’s the role of the FDA here? In the last 2 years, we have seen the inclusion of ECG on smartwatches, and as it’s a health feature, it’s important that smartwatches get approved by FDA for consumers.

Now the thing which FDA mainly tests is the accuracy of smartwatches when it comes to AFIB. As AFIB is highly sporadic, it means that smartwatches need to be very accurate and precise to detect it.

When it comes to getting approval from FDA, things get tough because the standards are pretty high, and only accurate algorithms get approval from the FDA.

So far, only a handful of companies have managed to get FDA approval which includes Apple, Fitbit, Withing’s, and Samsung.

Should I Rely On Smartwatches for AFIB Detection?

Smartwatches come with life-saving features such as Fall Detection, AFIB, and ECG, which can potentially save your life. On the internet, you will find hundreds of stories of the people who were saved by their smartwatches.

One particular story I would like to iterate here is the story of Peggy Reynolds, whose life was saved by a smartwatch with fall detection.

She was gifted this smartwatch three years back, and one fine Sunday, she fell and sustained a head injury. The watch alerted her daughter and medical responders immediately, and they were able to rescue her on time.

In the case of AFIB, your body won’t show any symptoms, but your watch is capable of detecting the condition, and if it detects, it will immediately notify you, and you can save yourself from a deadly stroke.

So, I would not recommend that you fully rely on your smartwatch, but you can surely use it as a tool to detect medical conditions at early stages.
