Long-Term ST (86 records)

The Long-Term ST Database contains 86 lengthy ECG recordings of 80 human subjects, chosen to exhibit a variety of events of ST segment changes, including ischemic ST episodes, axis-related non-ischemic ST episodes, episodes of slow ST level drift, and episodes containing mixtures of these phenomena. The database was created to support development and evaluation of algorithms capable of accurate differentiation of ischemic and non-ischemic ST events, as well as basic research into mechanisms and dynamics of myocardial ischemia. more...

Each of the 86 records 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.
