Long-Term ST Database expanded

The creators of the Long-Term ST Database have contributed half of it (43 of 86 complete records) to PhysioNet. Each record is 21 to 24 hours long, and contains 2 or 3 ECG signals, annotated beat-by-beat and with respect to ST episodes, rhythm changes, and signal quality changes; each record also includes ST level time series based on 16-second averages centered on each beat.
