ESC: Smartphone Makes a Smart Afib Diagnosis

ROME — The accelerometers and gyroscopes in a smartphone can do more for mobile health monitoring than measuring exercise or sleep, found researchers in an early study showing accuracy for diagnosing atrial fibrillation. A smartphone app using recordings from the phone, placed directly on the chest with no hardware or add-on device, had 98.5% sensitivity and 95.2% specificity for the arrhythmia, Tero Koivisto, MD, of the University of Turku, Finland, and colleagues reported here at the European Society of Cardiology meeting. The out-of-bag classification error in Random Forests, a measure of prediction error for machine learning models like the one used for the app’s algorithm, was 4.95%. The study included 16 patients with chronic atrial fibrillation from the Turku Heart Center and 20 recordings from healthy volunteers to validate the…
