In this study, a real-time fast parallelized processing
technique for C-point locations is presented. Singularity detector adopting
a multiscale wavelet transform is used for impedance cardiography signal
processing. Both theoretical analysis and experimental results show the
method reliability and sensitivity. Moreover, the algorithm noise immunity
has been tested adding Gaussian noise with a variable variance to the
real ICG signal. Test results with minimum interferences from noise and
artefacts have been obtained.
