sample waveforms

This database includes 28 ECG recordings of varying lengths, most of which were recorded during exercise stress tests and which exhibit transient ST depression. The last five records (323 through 327) are excerpts of long-term ECG recordings and exhibit ST elevation.

Note that the annotation files contain only beat labels; they do not include ST change annotations, as in the European ST-T Database.
