The output of ECGSYN may be employed to assess biomedical signal processing techniques which are used to compute clinical statistics from the ECG.ĮCGSYN was contributed to PhysioNet by Patrick McSharry from the Department of Engineering Science, University of Oxford, and by Gari Clifford of the Laboratory for Computational Physiology at MIT. Using a model based on three coupled ordinary differential equations, ECGSYN reproduces many of the features of the human ECG, including beat-to-beat variation in morphology and timing, respiratory sinus arrhythmia, QT dependence on heart rate, and R-peak amplitude modulation.

e215–e220.ĮCGSYN generates a synthesized ECG signal with user-settable mean heart rate, number of beats, sampling frequency, waveform morphology (P, Q, R, S, and T timing, amplitude,and duration), standard deviation of the RR interval, and LF/HF ratio (a measure of the relative contributions of the low and high frequency components of the RR time series to total heart rate variability).
