A multi-source feature dataset of 21-beat IBI segments for paroxysmal atrial fibrillation detection (16 ECG databases, 12 features)

This dataset contains 978,591 labeled 21-beat IBI segments with 12 features for paroxysmal atrial fibrillation detection, derived from 16 PhysioNet electrocardiogram databases. All details regarding data sources, preprocessing, feature extraction, quality control, and per-database statistics are fully described in the original publication:Song Y, Fan J, Yang Z, Jia Q, Zhao P.
