simulator of realistic ECG signal from rr data for matlab or python

Question

I have a series of rr data (distances between r-r peak in PQRST electrocardiogramm signal) and I want to generate realistic ECG signal in matlab or python. I've found some materials for matlab (ecg built-in function in matlab) but I can't figure out how to generate it from rr data, and I've found nothing for python. Any advice?

Answer 1

Does this suit your needs? If not, please let me know. Good luck.

import scipy
import scipy.signal as sig
rr = [1.0, 1.0, 0.5, 1.5, 1.0, 1.0] # rr time in seconds
fs = 8000.0 # sampling rate
pqrst = sig.wavelets.daub(10) # just to simulate a signal, whatever
ecg = scipy.concatenate([sig.resample(pqrst, int(r*fs)) for r in rr])
t = scipy.arange(len(ecg))/fs
pylab.plot(t, ecg)
pylab.show()
