Distribution of the 3 parameters for RR interval differences in the healthy volunteers and patients with AF. Criteria 1: {Max(RR)-Min(RR)}/Mean(RR) >0.2. Criteria 2: SD(RR)/Mean(RR) >0.1. Criteria 3: Mean[{RR-Mean(RR)}/Mean(RR)] >0.05. The cut-off value of each criterion was set to include AF maximally and to exclude all sinus rhythms in ECG measurements. AF was recognized automatically when all 3 criteria were satisfied. The same criteria were applied to the radar measurements to automatically detect AF using radar. *Diagnostic performance at each cut-off value.
