The result of the calculation is the positive predictive value: the probability of having atrial fibrillation when it is detected by the watch. This branch of statistics uses prior information, such as disease prevalence, to interpret the likelihood of an outcome, in this case having atrial fibrillation. I applied Bayesian statistics to this information. Peloton + Apple Watch heart rate integration To set up this feature, the first step is making sure that you have the Peloton app installed on both your iPhone and your Apple Watch. Apple helpfully supplies those numbers - 98 percent sensitivity and 99.6 specificity - in its user’s guide. Next I needed to know the sensitivity (the probability of having atrial fibrillation if the watch detects it) and specificity (the probability of not having atrial fibrillation if the watch does not detect it) of the Apple Watch app. According to the AnTicoagulation and Risk Factors in Atrial Fibrillation ( ATRIA) Study, which included nearly 1.9 million Americans, the percentage increases with age: 0.1 percent of those younger than age 55 have atrial fibrillation, rising to 9.1 percent among those over age 85. I first needed to know the baseline risk of having atrial fibrillation.
