Wavelet Analysis Of E.C.G. Signals
Lotfi Senhadji, Jean-Jacques Bellanger, Guy Carrault, Jean-Louis Coatrieux · 2005
The complete separation of relevant waves from the E.C.G. signals prior to interpretation is still an open problem because of the noisy nature of the input data.A preliminary attempt is proposed in this paper based on wavelet analysis. Decomposition procedures are reviewed and partial noiseless recomposition is explicited. Some results in low signal to noise ratio are provided.
