<H3>Abstract:</H3>
|
|
<DIV>
|
|
A dynamical model based on three coupled ordinary differential equations
|
|
is introduced which is capable of generating realistic synthetic
|
|
electrocardiogram (ECG) signals. The operator can specify the mean and
|
|
standard deviation of the heart rate, the morphology of the PQRST
|
|
cycle and the power spectrum of the RR tachogram.
|
|
In particular, both Respiratory Sinus Arrhythmia at the high frequencies
|
|
(HF) and Mayer waves at the low frequencies (LF)
|
|
together with the LF/HF ratio are incorporated in the model.
|
|
Much of the beat-to-beat variation in morphology and timing of the human
|
|
ECG, including QT dispersion and R-peak amplitude modulation
|
|
are shown to result. This model may be employed to assess biomedical
|
|
signal processing techniques which are used to compute clinical statistics
|
|
from the ECG.
