US researchers said that 98% of positives for AF were confirmed as correct when an ECG patch was then worn for a week in their study of almost half a million people.

The findings were reported to the American Heart Association Scientific Sessions 2021 virtual meeting by Dr Steven Lubitz of Massachusetts General Hospital, Boston, US.
