In a separate experiment, the watch accurately predicted AFib 84% of the time. On the flip side, some have cautioned that the watch may not be sensitive enough to catch some AFib. Only 13% of people who were later diagnosed with atrial fibrillation had gotten an irregular heart rhythm notice previously.
Then, can a smartwatch detect irregular heartbeat?
Research Highlights: A novel software algorithm developed for wearable devices, such as smartwatches and fitness trackers, was able to detect irregular heart rhythms.
Also know, can Apple Watch pick up heart palpitations?
Apple Watch customers have access to two software as medical device features to detect heart arrhythmias such as atrial fibrillation (AFib): the Irregular Rhythm Notification Feature (IRNF) and the ECG app.
Does Apple Watch automatically detect AFib?
In a study done by the Cleveland Clinic found that in a study of 50 postoperative cardiac patients, the Apple Watch Series 4 connected to a waveform PDF was about to detect 98% of AFib occurrences. In the same study, the Apple Watch display alone was only able to diagnose 41% of the instances of AFib.
How good is ECG on Apple Watch?
The ability of the ECG app to accurately classify an ECG recording into AFib and sinus rhythm was tested in a clinical trial of approximately 600 subjects, and demonstrated 99.6% specificity with respect to sinus rhythm classification and 98.3% sensitivity for AFib classification for the classifiable results.
What does a heart palpitation feel like?
Heart palpitations are heartbeats that suddenly become more noticeable. Your heart may feel like it’s pounding, fluttering or beating irregularly, often for just a few seconds or minutes. You may also feel these sensations in your throat or neck.
Which Apple Watch models work with irregular rhythm notifications?
Apple Watch Series 1 or later with watchOS 5.1. 2 sends a notification if an irregular heart rhythm such as AFib, is identified.
