How accurate is smart watch ECG?
The smart watch–generated ECGs were 93\% to 95\% accurate at correctly identifying and distinguishing between different types of heart attacks. Among the healthy people, the watch’s accuracy was 90\% for correctly noting the absence of a heart attack. The findings were published online Aug. 31, 2020, by JAMA Cardiology.
Do smartwatches give accurate heart rate readings?

Can a smartwatch detect irregular heartbeat?
Novel algorithm on wearable devices can detect irregular heartbeat, may prompt early care. Research Highlights: A novel software algorithm developed for wearable devices, such as smartwatches and fitness trackers, was able to detect irregular heart rhythms.
Can ECG detect heart problems?
