Denoising of T Wave Using Wavelet Transform

K. Srinivas; P. Chandra Sekhar

A Wavelet transform based denoising of T Wave is proposed in the work. The T wave is denoised with fixed form threshold, Rigorous SURE, Heuristic SURE threshold methods. Daubechies wavelets at different levels are used in the work. The Simulated results obtained from the data collected from MATLAB based ECG simulator and data recorded from 8 Channel Physiograph. It is observed that for hard thresholding the standard deviation is very much decreased with scaled noise.
