For specificity, the value reaches 94% (95% CI: 89%–97%).How Accurate Are the Algorithms Used within Smart Watches at Detecting Atrial Fibrillation? Smart watches use algorithms to detect signs of atrial fibrillation from the ECG they record. Their sensitivity (true positive rate) and specificity (true negative rate) generally range from 70–90% in clinical trials.
