The Apple Watch is the smartwatch to beat . It ’s massively popular , has a full orbit of features , and compared to some of its competitors , leads the way in rethinking how wearables can work within the health sphere . During the Apple Watch share of Apple events , you may generally ask a feel - good reel of real - life user sharing stories of how the watch saved their lives by notifying them of their unpredictable heartbeat . That said , Apple’sown FDA applicationfor itsECGapp admit the watch does not detect atrial fibrillation ( AFib ) for heart rates outmatch 120 beats per minute — a limit that aForbes reportsuggests could leave a declamatory number of Apple Watch users with a imitation sense of security measures .
That 120bpm limitation is , as it turns out , significant , according to Forbes . Mayo Clinicsays that the nitty-gritty rate of AFib patients can roam anywhere from 100 to 175bpm — have in mind the Apple Watch is n’t looking at a decent chunk of common people who may be impress . Furthermore , this2015 studynotes that the miserly heart and soul charge per unit of new - onset AFib patients is 109 beats per minute , with a third of patient having heart rates above 120 bpm . Anotherjust - issue studyin Circulation remark the Series 4 correctly name AFib in 34 of 90 cases , for an accuracy charge per unit of 41 percent .

By itself , those results are n’t damnatory , per se . They are , however , sobering for anyone high-pitched on the idea that ECG on the wrist will save a loved one ’s life . It might . There ’s also a good prospect it might not . AFib is a sly complaint that goes largely undetected for a understanding . It ’s also deserving bring up that in Apple ’s FDA compliance , it has purposefully define essence rates above 120 bpm and under 50 bpm as “ unclassified ” and that repeated results in this cooking stove upshot in a telling stating that user should perhaps assay out a Dr. . This is likely Apple erring on the side of caution , and it is n’t necessarily indicative of the vigil ’s capabilities . After all , many of the anecdotal stories of just - in - clock time Apple Watch presentment ask higher - than - intermediate heart rates .
On this front , eagle - eyed referee wo n’t be surprised . Ever since the Series 4 introduced ECG capacity , Apple has always emphasize in the fine print that the Series 4 and Series 5 are not symptomatic tools . Also , unbelieving consumers will also remember that the FDA only granted the ECG app de novo clearance — imply it ’s a novel equipment that ’s unlikely to cause widespread trauma , but not a full - flight FDA - approved aesculapian intersection . That tenuous difference in semantics subject because Apple ’s current ECG software is n’t the type of tech that would undergo the “ approval ” summons reserved for Class III products like implantable pacemakers . And that ’s okay ! But it ’s important to avoid conflating ECG software that ’s meant to enkindle cognizance with more rigorously regulated devices .
Frankly , erring on the side of caution is a good thing when it make out to wearable tech toeing the assembly line between wellness and aesculapian devices . Apple deserves credit for conducting massive , magnanimous - scale clinical study with reputable partners to figure out how this tech can be applied to detect new information . This special category isrife with pseudoscienceand plenty of shady wellness tech companies attempt to pass off white papers and inner “ enquiry ” as rigorous clinical study — and that ’s really concerning . It ’s just that even as Apple does participate in all these studies , there are still huge questions surround how the finding get integrated into the greater healthcare system of rules , patient role ’ health datum privacy , and a slew of other circumstance . For example , it ’s not clear if everyday Apple Watch users know how to correctly interpret their data , or if family physician even know how to handle patients who demand a checkup because their watch separate them they postulate one .
That said , it is also worth casting an incredibly critical eye toward any study meant to prop up a consumer product ’s authenticity . Apple just latterly announced it’spartnering with Johnson & Johnsonto research AFib and see if it can prognosticate strokes in seniors . That ’s in force for many reasons , admit the massive scale of the bailiwick . The field of study is also one of the first to involve big technical school , gravid pharma , and a big retailer in Best Buy — whether that ’s good or big calculate on your eyeshot of those industries . You also have to deal Apple has beenin talks with health insurersto allow for discounts on spotter . That ’s not a cause to immediately riff out , but uh , no one wants that dystopian future where you ’re incentivized to employ a wearable to get better health insurance charge per unit — or else .
But that ’s all looking down the road . At best , health wearable are peaceful monitoring devices that take into account you to be more mindful of your average . Right now , it ’s always helpful to remember that vesture are not a substitute for confabulate your doctor and to treat any radical claim as exhuberent marketing .
