Apple Watch may spot heart problem, but more research is needed

USATODAY - Tech Top Stories

A New Jersey woman is alive because her Apple Watch alerted her to an elevated heart rate. It turned out she had fluid around her heart from a viral infection. WASHINGTON – A huge study suggests the Apple Watch can detect a worrisome irregular heartbeat at least sometimes – but experts say more work is needed to tell if using wearable technology to screen for heart problems really helps. More than 419,000 Apple Watch users signed up for the unusual study, making it the largest ever to explore screening seemingly healthy people for atrial fibrillation, a condition that if untreated eventually can trigger strokes. Stanford University researchers reported Saturday that the watch didn't panic flocks of people, warning just half a percent of participants – about 2,100 – that they might have a problem.

Apple's Heart Study Is the Biggest Ever, But With a Catch


Last November, Apple Watch owners began receiving recruitment emails from Apple. The company was looking for owners of its smartwatch to participate in the Apple Heart Study--a Stanford-led investigation into the wearable's ability to sense irregular heart rhythms. Joining was simple: Install an app and wear your watch. If the watch's optical sensors detected an arrhythmia, you might be shipped a dedicated heart monitor--a benchmark to compare against readings from your Apple Watch--to wear for seven days. In true Apple fashion, enrollment and participation were designed to be as user friendly as possible: "Apple and Stanford Medicine are committed to making it easy for people to participate in medical research," the research partners wrote, "because more data can lead to discoveries that save lives."

Arrhythmias-Detecting Apple Watch: Apple Partnering With Stanford, American Well For New Project

International Business Times

Apple has decided to partner with Stanford and American Well for its new project that involves its Apple Watch smartwatch. The Cupertino giant is apparently looking to expand the usefulness of its wearable into the field of medicine by determining if its Apple Watch's sensors can detect arrhythmias or abnormal heart rhythms. On Monday, CNBC ran a story on how Apple partnered with a group of clinicians at Stanford and telemedicine vendor American Well for a new project. The ultimate goal of this project is to find out whether the heart rate sensor in the Apple Watch is capable of detecting abnormal heart rhythms among patients. The publication cited sources who reportedly asked not to be named for the plan has yet to be disclosed publicly by the parties involved.

Apple Watch detects heart problem known to cause strokes

Daily Mail - Science & tech

The Apple Watch has been found to detect a heart condition that affects some 2.7 million people in the US, a new study has revealed. By pairing the smartwatch's heart rate sensors with artificial intelligence, researchers developed an algorithm capable of distinguishing an irregular heartbeat, known as atrial fibrillation, from a normal heart rhythm - and with 97 percent accuracy. Atrial fibrillation, although easily treatable, has been difficult to diagnose and the team believes their work could pave the way for new methods to identify the abnormality. The Apple Watch has been found to detect a heart condition that affects some 2.7 million people in the US, a new study has revealed. The algorithm was accurate 97 percent of the time using the smartwatch's heart rate sensor (stock) University of California, San Francisco, in collaboration with the app Cardiogram, trained a deep neural network with heart readings from 6,158 Cardiogram users.

Apple Watch ECG app: How it works and what it means for the future of health


Apple has long been positioning the iPhone and the Apple Watch as wellness devices -- hardware that can help you track markers of fitness including exercise, step count, and even sleep and'mindfulness minutes'. Also: Apple Watch ECG app launches today with watchOS 5.1.2 But now it's taking that a step further by adding the sort of heart-monitoring technology more usually of interest to doctors -- making it available to anyone with a wrist and a few hundred dollars to spare. While previous versions of the Apple Watch have been able to measure a wearer's heart rate, the Apple Watch 4 takes a big step up with its electrocardiogram (ECG or EKG depending on where you are) functionality -- which is now live. Thanks to the new functionality, the Apple Watch will be able to keep an eye on your heart in two ways.
