A Decision-Making System with Reject Option for Atrial Fibrillation Prediction Without ECG Signals

•An evidential decision-making system for Atrial Fibrillation prediction.•Handling uncertainty and missing data.•Reject decision if available data are not sufficiently informative.•No use of ECG like most systems, but low frequency sampled physiological signals.•Competitive performance with much less data, favoring a portable device solution.
