A slightly smarter Apple Watch could detect signs of a stroke


Researchers have now proven that the Apple Watch’sheart rate sensors are no gimmick( if that still needed demonstrating ). Combined with some advanced AI, an Apple Watch-based learn was able to detectwearers with an irregular heartbeat with 97 percent accuracy. In the near future, physicians could use such asolution to catch the onset of astroke in at-risk patients.

Researchers from University of California San Francisco and software engineers from the app Cardiogram employed a preliminary algorithm to find whether wearers had atrial fibrillation( AF ). People with AF have an irregular, randomized nerve beat pattern. While it’s often altogether asymptomatic, in a number of cases, it can lead to stroke. Catching it early, affected patients can undergo a cardioversion procedure, which returns nerve rhythms back to normal.

The team tested their algorithm on 51 individuals before and afterundergoing a cardioversion. Compared to a hospital grade 12 -lead ECG, the Apple Watch was 97% accurate in identifying AF.

To get to that level, the researchers and technologists first had to develop an accurate algorithm, though. They did this through the Apple Watch-basedmRhythm learn. Of 6,158 Apple Watch consumers recruited viathe Cardiogram app, 200 participants had an AF condition. The researchers employed data from those individuals to recognise what indicates normal heart rate and normal heart rate variability, and what markers indicate signs of AF.

News like this could be just what the smartwatch industry needs to give it a boost. After reports that sales were tanking late last year, smartwatch adoptionisprojected to grow this year. Health and fitness-tracking are one of the key use occurrences for buyers, and studies like this give concrete proof that a one-time $300 acquisition could pay dividends in the long run.

The mRhythm learn is still open to Apple Watch, Android Wear, and other smartwatch owneds. If you want contribute your own data to the mix, you are able to psyche to its website to sign up.
