Normal Sinus Rhythm RR Interval Database

The new PhysioNet website is available at: https://physionet.org. We welcome your feedback.

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.

For additional data of this type, including digitized ECG signals, see the MIT-BIH Normal Sinus Rhythm Database.

We thank Phyllis Stein, of Washington University School of Medicine, St. Louis; and Rochelle Goldsmith, of Columbia-Presbyterian Medical Center, New York, for their generous contributions of these data to PhysioBank.
