Can Researchers Detect Irregular Heart Rhythms with the Apple Watch?
An anonymous reader quotes USA Today: Might wearing an Apple Watch save you from a stroke or cardio problem? Apple is careful not to make that direct claim. But the company, in collaboration with Stanford University School of Medicine, launched the Apple Heart Study app on Thursday that uses the heart rate sensor inside the Apple Watch to collect data on irregular heart rhythms... If an irregular heart rhythm is detected, participants in the study will be notified through the Apple Watch and on their iPhones. Should that occur, you'll be offered a free consultation with a study doctor, and possibly an electrocardiogram patch for additional monitoring... A participant in the study merely has to download the app and wear the watch... The way Apple explains it, a sensor inside the watch uses green LED lights flashing hundreds of times per second and light-sensitive photodiodes to detect the amount of blood flowing through the wrist. The sensor has an optical design that gathers signals from four distinct points on the wrist. Using software algorithms, the Apple Watch can isolate heart rhythms from other noise, and identify an irregular heart rhythm. The FDA has also approved the first personal electrocardiogram accessory for the Apple Watch, according to TechNewsWorld. "The KardiaBand" also detects and records atrial fibrillation that can lead to strokes or other heart problems. "The user simply touches an integrated sensor, and the results are then displayed on the face of the Apple Watch." An irregular, bloodflow-disrupting heartbeat is the top cause of strokes, which kill 130,000 people every year just in the U.S. -- in many case before they've experienced any symptoms.Read more of this story at Slashdot.
