Example of ECGSYN output

The files in this directory illustrate ECGSYN output obtained using its default settings. The files ecgsyn.dat and rr.dat are created by ECGSYN itself.

ecgsyn.dat is a text file, which contains three columns:

• the time in seconds
• the ECG amplitude in millivolts
• markers to indicate the locations of the waveform peaks:

  0	(no peak)
  1	Top of P-wave
  2	Q-point
  3	Peak of R-wave
  4	S-point
  5	Peak of T-wave

The files syn.hea and syn.dat are PhysioBank (WFDB) format header and signal files created from the ECGSYN output by:

    wrsamp -F 256 -o syn -x 200 1 <ecgsyn.dat

The file ecgsyn.png (shown below) was created from the first 4.5 seconds of ecgsyn.dat, using plt:

     plt ecgsyn.dat 0 1 -xa 0 4.5 -t "ECGSYN output" \
       -x "Time (s)" -y "ECG Amplitude (mV)" -T lw | \
     lwcat -png >ecgsyn.png
