Details

The following text is reproduced (abridged) from PhysioBank, page http://www.physionet.org/physiobank/database/aami-ec13/. Other recordings belong to the dataset and can be obtained from the same page.

The files in this set can be used for testing a variety of devices that monitor the electrocardiogram. The recordings include both synthetic and real waveforms. For details on these test waveforms and how to use them, please refer to section 5.1.2.1, paragraphs (e) and (g) in the reference below. Each recording contains one ECG signal sampled at 720 Hz with 12-bit resolution.

Note

Timestamps in the datasets have been re-created at the indicated frequency of 720 Hz, whereas the original timestamps in ms (at least in text format) only had three decimal digits' precision, and were therefore affected by substantial jittering.
