A pocket-sized monitor that takes an ECG can help detect cardiac arrhythmia in patients with palpitations and pre-syncope who get sent home from the ED without a diagnosis, a study shows.
Such patients were 10 times more likely to have a serious condition detected if they had the device that wirelessly connects to an app on their smartphone to record heart rhythm events, according to British researchers.
