Study finds Apple Watch can detect heart problems with 97% accuracy - A wearable could save your life 

 By Rob Thubron on May 12, 2017, 10:00 AM

Fresh from the news that its Apple Watch has helped the Cupertino company oust Fitbit as the world’s top wearables vendor, a new study suggests the device could have an unexpected use: Detecting abnormal heart rhythms.

A study by researchers from the University of San Francisco presented at Heart Rhythm 2017 reveals that the heart sensor built into the Apple Watch could be used to detect conditions like arrhythmia and atrial fibrillation (AF) with 97 percent accuracy.

Over the course of several months, the researchers gathered data from 6158 users of the Cardiogram app for the Apple Watch. 200 of the subjects had been diagnosed with paroxysmal atrial fibrillation. The engineers used the data to feed a deep neural network that learned to distinguish between a healthy heartbeat and AF.

The system was tested on 51 hospital patients set to undergo cardioversions, a procedure that restores the heart’s normal rhythm. By wearing the Watch and using the app for 20 minutes before and after the operations, it was found that the AI correctly detected AF 97 percent of the time.

“Our results show that common wearable trackers like smartwatches present a novel opportunity to monitor, capture and prompt medical therapy for atrial fibrillation without any active effort from patients,” Dr. Gregory Marcus, Director of Clinical Research at UCSF’s Division of Cardiology, said in a statement.

2.7 million Americans suffer from AF, according to the American Heart Association. It leads to blood clots, stroke, heart failure and other heart-related complications. With the illness being quite difficult to diagnose, wearables like the Apple Watch could help save lives.

“While mobile technology screening won’t replace more conventional monitoring methods, it has the potential to successfully screen those at an increased risk and lower the number of undiagnosed cases of AF,” Marcus added.

How much accurate would be an Apple watch versus a Fitbit watch with HR? I'm wondering because this has been extremely useful for tracking a lot of different activities throughout the day, even if you are not a fit enthusiast or just a casual guy who wants to set some goals for the day.

"How much accurate would be an Apple watch versus a Fitbit watch with HR?"

That's exactly what I was wondering because as long as they both have the hardware to track the person's heartbeat, the rest is software based (and it doesn't matter if it's an Apple Watch or not).

Basically, praising the Apple Watch for doing something any device with HR hardware seems odd. Is there something I'm missing?
