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.
