Normal Sinus Rhythm RR Interval Database (NSR2DB, PhysioNet)

NSR2DB holds beat annotations for 54 long-term ECG recordings of people in normal sinus rhythm: 30 men aged 28.5 to 76 and 24 women aged 58 to 73. The original ECGs, which are not included, were digitized at 128 Hz, and the beats were annotated automatically and then reviewed by hand.

Original description

This database includes beat annotation files for 54 long-term ECG recordings of subjects in normal sinus rhythm (30 men, aged 28.5 to 76, and 24 women, aged 58 to 73). The original ECG recordings (not available) were digitized at 128 samples per second, and the beat annotations were obtained by automated analysis with manual review and correction.
