The watch’s heart monitor is a long way from a medical-grade device, but smart software may be able to improve its capabilities.

    The Apple Watch is not a medical device. Sure, it can keep an eye on large changes in your heart rate, making it reasonably good at telling you how long you worked out for. But anything more than that is .

    Which is why it’s interesting that on Thursday, a study emerged suggesting that readings from an Apple Watch can indeed be used to detect atrial fibrillation—a worrisome heart condition that, if the sufferer isn’t hooked up to a heart monitor, often produces no noticeable symptoms.

    The the trick behind the study, which was conducted by Greg Marcus and a team of researchers at the University of California, San Francisco, and a startup called Cardiogram, was that it used artificially intelligent software to tease information out of the Apple Watch data.

    To do that, the researchers gathered data from 166 people who met several criteria: they wore an Apple Watch, were known to have atrial fibrillation, and also had an AliveCor device, an FDA-approved electrocardiogram (EKG) that hooks up to an iPhone (the company is also developing , but that hasn’t yet received FDA approval).

    Each of these users generated two streams of data simultaneously: one from the watch, and one from the EKG that was capable of accurately showing when someone’s heart was fibrillating. By training a machine-learning algorithm on the two streams, the team reasoned the algorithm could teach itself to identify what fibrillation looked like in the less precise Apple Watch data. A test on readings from about 50 people seemed to bear that out—the algorithm was 97 percent accurate in flagging fibrillation.

    It’s an encouraging result, but far too small a sample size to declare success. The study also suffered from some limitations that will hamper real-world implementation. The subjects had to remain still while taking readings, for example, because Apple has said that .

    Cardiogram, which has $2 million in funding from Andreessen Horowitz and others, , is entering a field that’s been riddled with problems. Just ask the people behind Quanttus, a startup that got a hard lesson in .

    It’s also a field that has competition. Alphabet’s health-tech company, Verily, is building what it calls a “Cardiac and Activity Monitor” that likely has an EKG on it, among other capabilities—part of a large-scale health study that Verily is conducting. , it appeared to be built specifically for tracking people’s health, rather than consumer use. It was plain-looking, and had an e-ink display that preserved battery life, so people could wear it for much longer stretches than Apple’s offering, which, after all, is really just a gadget.
