\details{
  

The following text is reproduced (abridged) from PhysioBank, page
\url{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.
