The U.S. Food and Drug Administration has given the KardiaBand its stamp of approval, AliveCor announced Thursday. The device is the first FDA-cleared personal electrocardiogram (EKG) accessory designed for use with an Apple Watch.
The Kardiaband allows users to take EKG readings in order to distinguish between normal sinus Heart rhythms and atrial fibrillation (A-fib), the most common type of serious heart arrhythmia, which can lead to strokes or other heart-related problems.
The KardiaBand can record an EKG in just 30 seconds. The user simply touches an integrated sensor, and the results are then displayed on the face of the Apple Watch.
AliveCor also announced the release of SmartRhythm, a new feature in the Kardia app. It relies on artificial intelligence to monitor a user's heart rate and determine the "KardiaBand paired with SmartRhythm technology will be life-changing for people who are serious about heart health," said Vic Gundotra, CEO of AliveCor. Gundotra previously helmed Google+.
"These capabilities will allow people to easily and discreetly check their heart rhythms when they may be abnormal, capturing essential information to help doctors identify the issue and inform a clear path of care to help manage A-fib, a leading cause of stroke, and other serious conditions," he added.
KardiaBand, which is now available for US$199, works in conjunction with AliveCor's Premium $99 a year subscription service. The combined system provides subscribers with SmartRhythm notifications on Apple Watch, unlimited EKG recordings, and automatic detection of A-fib or normal sinus rhythms.
Users can email unlimited EKG readings to anyone, including a doctor, and are provided with unlimited cloud access to all EKG readings, along with weight and medication tracking. All of this data is mailed to users in a monthly paper report with full readings from the device.correlation between heart activity and physical activity. It can detect when a user's heart rate and activity are out of sync and promptly send an alert.
Heart of the Matter
Although AliveCor's KardiaBand is the first EKG device available for the Apple Watch, it is just a small part of Apple's fitness-monitoring efforts.
The company recently announced its Apple Heart Study app, the first research study to utilize Apple Watch's heart rate sensor to collect data on A-fib. Apple partnered with Stanford Medicine to perform that research. Smartwatches could become increasingly useful to help monitor heart-related medical issues.
"There are millions of people with frequent or infrequent heart arrhythmia who could benefit from a band like KardiaBand," said Roger Entner, principal analyst at Recon Analytics.
"It would help diagnosis and speed up treatment in cases where and when it occurs, and it would certainly be a driver for people who have heart arrhythmia, which is often a side effect of diabetes and other heart disease," he told TechNewsWorld.
Health and Technology
One issue might be how easy, convenient and even comfortable such a device would be to wear, especially for extended periods. Further, some users might rely on these devices as replacements for regular doctor's visits.
"It's fine to instrument a person, as it enables closer monitoring," suggested Roger Kay, principal analyst at Endpoint Technology Associates.
"In general, early warning gives more information and is mostly not too invasive, but of course people still need to be treated by healthcare professionals" he told TechNewsWorld.
"The app can't do anything but tell you what's going on at a detailed level, so it makes sense for people at risk," Kay noted. Still, "the device and app are a diagnostic tool to make it easier to treat, not a replacement for treatment," Recon Analytics' Entner added. "Only a doctor can do that."
Widening the Market
As health costs continue to rise, smartwatch monitoring devices could offer some financial benefits. Users might not feel the need to rush to the emergency room every time they felt slightly off.
It's possible that health and fitness monitoring devices will continue to become more highly specialized.
"This is the old 'Swiss Army Knife' versus dedicated function wearables debate," explained Robin Raskin, founder of Living in Digital Times.
"From my point of view, smartwatches won't really take off until they have some super useful functionality in the workplace, like payments or physical access to buildings and computers," she told TechNewsWorld.
"That said, AliveCor builds great products -- and this one, I'm sure, works well," added Raskin.
More widespread acceptance may come via a mobile phone attachment, however, so it is unlikely that KardiaBand will broaden the smartwatch market, suggested Raskin.
"I don't think too many people would buy and wear a device like the KardiaBand without the need," added Entner.
