Best Smartwatch for AFib in 2021

A smartwatch with AFib (Atrial Fibrillation) monitoring makes it easier than ever before. A new generation of apps is available on smartphones and smartwatches that can detect and measure AFib.

AFib is the most common complication in the heart’s electrical system. It is a type of arrhythmia (irregular heartbeat) that could increase your risk of stroke. 

A-fib affects somewhere between 3 million and 6 million Americans, most of them over age 65. In some people it’s silent, causing no symptoms. In others, it causes heart palpitations, dizzy spells, and shortness of breath. Whether or not a-fib causes symptoms, it quadruples the risk of having a stroke

Smartwatches & Fitness Trackers that can Monitor AFib

To diagnose Atrial Fibrillation, your doctor may review signs and symptoms and your medical history, and conduct a physical examination. The process of diagnosing may extend to several physical tests.

In all the ways, an AFib smartwatch helps a lot in keeping track of your heart rhythms. 

1. Apple Watch Series 5: All-in-one Medical Watch for AFIB

The Apple heart study released in March 2019, conducted at Stanford University, looked at 400,000 volunteers who had an apple watch on their wrists to test the new technology of detecting the wearer’s pulse and measuring the blood flow. The participants were AFib patients.

From the study, researchers came across the conclusion that wearable Apple watches technology can successfully identify heart rate irregularities.

Last year, Apple CEO Tim Cook tweeted that how an apple watch saved the life of an 18-year-old girl who said the device was the fortunate cause of saving her life.

Optical HR Sensors: Flashing Light on the Wrist

Actually, Apple is getting sued for encroaching on a patent that uses Optical HR sensors for detecting AFib.

How optical heart rate sensors work?

Smartwatch uses heart rate sensors for AFib. When blood circulates throughout the body, it causes changes in the tissues. Optical heart rate measurement uses light to measure these tissue changes. Hearts beat with a certain volume, low blood volume causes in returning more light whereas high volume results in returning less light to the optical sensor.

By taking time into account between high and low light returning intensities, the device measures beat-to-beat data. This data is used as raw data in calculating the heart rate.

Now, the question arises how light can do this? If it’s a bit confusing for you ___ let’s simplify it.

It’s quite easy to demonstrate. Put a flashlight on your fingertip. It looks entirely red. But with a perfect light sensor, you can easily notice that the intensity of redness varies according to one’s heartbeat.

Although it is expensive it worth it. If you don’t want to spend more money then you can also use the Apple watch series 4.

Smartwatch Buying Guide for AFib: Bonus Tips 🔥

But choosing a watch that has nothing to do with ECG will not work for AFib enthusiasts. So, with this mindset, choose one for you as your health companion would worth your life.
 
  • Pick a watch with GPS and heart rate sensors. These are the basic needs for an irregular AFib patient. These help in walk and other outdoor activities tracking.
  • Buy a watch compatible with your smartphone. apple watches only work with iPhone while Google’s wear OS and Samsung watches work for both iPhone and Android phones.
  • Pick a smartwatch with greater battery timings. Analog watches are more optimized and have the longest battery life. But these do not have touch screens and multiple important features needed for AFib detection and monitoring.

The Danger of AFib and Consequences

Although it seems weird and frightening, an “attack of AFib” is not as harmful by itself. But the real danger is the rise in the danger of stroke. AFib can greatly increase the risk of stroke and other heart-related problems.

It has been said in a clinical case report published by John Wiley and Sons Ltd states: “Atrial fibrillation (Afib) is associated with 15%‐25% of strokes.” In this case tech accessories like Apple’s, Samsung’s, and other Fitbit’s editions are greatly encouraged for their ECG. It can increase the probability of detection of AFib and hence causing more chances of saving a life. Early diagnosis and treatment decrease the risk of stroke.

AFib leads to Heart Failure

Heart failure means the heart is not pumping enough blood to meet the body’s needs. In AFib, heartbeats irregularly, faster so that it never properly fills up the blood in the required amount to throwing in the body.

As a result, when the heart never pumps the blood efficiently with strong contraction and relaxation, symptoms develop.

Conclusion

There is crystal clear evidence of smartwatches saving lives, but these are not medical equipment. Smartwatches are capable of detecting AFib, but these infallible and not a substitute for a trained cardiologist.

Apple and Galaxy watches are good at detecting AFib. Firstly, you should go with Apple watches due to their reliability and durability. Along with the fact, Apple is the world wide largest tech brand. Samsung Galaxy watches are another pick for android users.
