Study confirms that the Apple Watch saves lives

Study confirms that the Apple Watch saves lives
A large study sponsored by Apple has revealed that the Apple Watch can detect an irregular heartbeat. 400,000 Apple Watch users were invited to take part in the study and the results were presented today in New Orleans at a meeting of the American College of Cardiology. 2,000 participants, or .5% of those wearing the smartwatch, received a notification about an irregular pulse. The 2,000 were sent a patch for their Apple Watch that included an electrocardiogram (ECG) sensor to help detect atrial fibrillation (AFib).

AFib, which is an irregular heartbeat, can lead to strokes, blood clots, heart failure and other serious issues. AFib contributes to 130,000 deaths a year in the U.S. The Apple Watch series 4 already includes an ECG monitor right out of the box, but the study was completed before this new variant of the timepiece was released. Returning to the study, about 33% of the 2,000 study participants who were flagged with an irregular pulse were told that they had AFib, according to the ECG patch that they were sent. 

57% of the Apple Watch wearers in the study sought medical help when they received a warning about an irregular pulse. That number might surprise consumers since it means that 43% of Apple Watch wearers in the study ignored the warning. Dr. Mitesh Patel, an assistant professor of medicine at the Perelman School of Medicine, noted that while the Apple Watch is good at detecting warning signs of heart disease, the watch needs to be combined with something that will motivate users to act on these warnings. In other words, receiving a warning without following up on it could prove fatal to the user.

When an Apple Watch wearer in the study received a notification of an irregular heartbeat, the notification would ask the participant to schedule a telemedicine appointment with one of the doctors associated with the study. At that point, the ECG patch would be sent to those receiving the notification, and was used to record the rhythm of their heart for up to one week.

Only 57% of study participants receiving an irregular pulse notification sought medical help


The researchers behind the study said that Doctors need to be careful when using data from consumer devices when treating patients. On the other hand, a Boston cardiologist named Dr. Deepak Bhatt said that the study was very important because more people will be wearing wearable devices in the future.


Apple plans on making a big push into healthcare, and the Apple Watch is at the vanguard of this decision. While the series 4 model includes an ECG monitor along with the heart rate monitor that all Apple Watch models have, the company is working on a way for the Apple Watch to show a user's blood glucose reading without a needle stick. This reading is used by diabetics to determine how much insulin they need to inject to bring their blood sugars down to a normal level. Currently, diabetics need to draw blood and place a drop of it on a test strip inserted into a glucometer to get a reading. This test is done several times a day. If Apple succeeds in producing a non-invasive blood glucose test for the Apple Watch, this alone could help Apple stay on top of the smartwatch market.

You cannot take any article seriously that praises a product, and the study is sponsored by the manufacturer! Grow a brain.

Are we Android users going to run out and buy Apple watches and iPhones considering you can get both (Android Wear and phone) for up to $1000 off when choosing Android powered devices? Nice try, Apple!

Or people who already have an iPhone can get one. No one said this article is targeted android users. What's with the "we"? You prop yourself up as the spokesman for android users? Get down from your soapbox.

I’m an android user, I’m also an Apple Watch/iPhone user, and I think what Apple is doing with the Watches health features is awesome.

You should only do whatever you feel like doing. Some things will make your health better, others are going to get you closer to your grave; as long as you are free to choose to do those things you must respect a Apple Watch buyer's right to do whatever he/she feels like.

If you don’t like apple that’s fine. It’s not like Samsung and other high end android phone are not equivalent or close in price. If you are invested in android it would be an expensive maneuver to go to iPhone. Same with me to go android. I am invested in iPhone products so to go to android and have to redo where I store my stuff, the apps I bought and so on would be expensive and not worth it. The phones are to similar to want to spend that much money. All good things will come to both sides of the isle at some point. Enjoy what you have and stop saying negative crap all the time about other manufactures. They both are great phone options.

I’m still confused as to why haters(Android users) read/comment on Apple articles?

its the same thing as haters (apple users) read/comments on android (mainly samsung) articles. they both have a inferiority complex or small d problem.

It’s probably the same as you reading and commenting on their comments. See how that works? Freedom of speech, to a point. Should we all just agree that Apple is super awesome bestest EVAR, and perfect? Hey, we can even close the comment section entirely! What’s the deal with anyone who disagrees automatically being labeled a “hater”, anyway? Is everyone sensitive these days?

No, but you should understand that your chances to die are higher, if you happen to have an accident while you drive your classic.

this is like the thousandth ''apple watch and life saving'' article i'm seeing on this site. I understand weekends are slow but really? How is this article newsworthy? Does nothing else happen in the tech world that you have to keep posting about the same topic every now and then?

No-one force you to read these?

An independent study concluded that the Apple Watch 4 actually has an over 90% false positives ratio. It's good at detecting AFib when you actually have it. It's shockingly inaccurate if you don't however.

i know, but it's something that i see and i have to point out. What do you think this comment section is for?

So you say phonearena can't publish this same article which sites like verge, reuters, cnn, theguardian, engadget, Bloomberg, menshealth and many others did?

If only apple made it android compatible and a better battery life i would buy it but I will wait for the pixel watch and see what it has to offer as the galaxy watch is not enough for me

They could probably count non-Apple devices as life-saving too, like in PA's arrow piercing article.

It says all "A large study sponsored by Apple ".
