They cite a recent survey indicating that as many as one in five AmericansВ owns a wearable fitness tracker. The researchers point out thatВ smartwatches like the Apple Watch present a novel opportunity to diagnose hard-to-detect illnesses. Gregory Marcus, Director of Clinical Research at UCSFвЂ™s Division of Cardiology, said in a statement. вЂњOur results show that common wearable trackers like smartwatches present a novel opportunity to monitor, capture and prompt medical therapy for atrial fibrillation without any active effort from patients,вЂќ Dr. That is higher thanВ any previous algorithm.

Each wore an Apple Watch with the Cardiogram app for 20 minutes before the procedure and 20 minutes after and found that the AI correctly detected atrial fibrillation 97 percent of the time. The studyвЂ™s authors validated the neural network against a subgroup of 51 patients set to undergo cardioversion, a medical procedure that restores the heart to a normal rhythm. The data wasВ used toВ train a deep neural network, a human-like form of AI, to distinguish between atrial fibrillation andВ a normal, healthy heart rhythm. Researchers recruited more than 6,000 users of the Cardiogram app for Apple WatchВ and collected more than 139 million heart rate measurements and 6,338 mobile electrocardiograms - records of the heartвЂ™s electrical activity - over the course of several months. Researchers at the University of California, San Francisco Division of Cardiology paired an artificial intelligence with the Apple WatchвЂ™s photoplethysmographic (PPG) sensors - the LEDs that record heart rate - to build an algorithm that could detect conditions like arrhythmia and atrial fibrillation (AF).ДЄtrial fibrillation, which affects more than 2.7 million American adults, was the studyвЂ™s principle focus. That is according to a study presented at Heart Rhythm 2017, the Heart SocietyвЂ™s 38th Annual Scientific Sessions, on Thursday. Julian Chokkattu/Digital TrendsTurns out the Apple WatchВ is good for more than just telling the time, tracking steps, and dictating text messages.
