RR interval analysis for detection of Atrial Fibrillation in ECG monitors.

We investigate two RR irregularity measures suitable for Atrial Fibrillation (AFIB) detection in ECG monitors, one based on the absolute deviation and the other based on the difference between successive RR intervals. A sequence of RR intervals is fed to the irregularity measures after applying certain constraints on length and beat classifications to provide criteria for detection of AFIB. Receiver Operating Curves (ROC) are used to analyze and compare the performance of the two methods against MIT-BIH Arrhythmia Database, MIT-BIH AFIB Database and a proprietary AFIB Database.
