"PAF prediction challenge and NSR RR-interval database"

"This dataset entry supports research on atrial fibrillation (AF) prediction using ECG-derived RR interval signals. The study utilizes publicly available datasets from PhysioNet, including the PAF Prediction Challenge dataset and the NSR RR-Interval database. The original datasets are not redistributed; instead, this entry provides a structured description of the data preprocessing pipeline. The methodology involves segmentation, filtering, R peak detection, extraction of RR intervals from ECG signals, and feature extraction. The dataset is intended for developing and evaluating AF prediction models and improving reproducibility of experimental results. Users are directed to access the original datasets through PhysioNet and follow the described preprocessing steps. All usage must comply with PhysioNet data access policies."
