ECG Performance
Clinical performance
The ECG algorithm ability to accurately classify an ECG
into AFib and sinus rhythm was tested in a clinical trial of
115 subjects. Rhythm classification of a 12-lead ECG by a
cardiologist was compared to the rhythm classification of
a simultaneously collect ECG from BPM Core.
