In this work we proposed a new method and a swift one of optimizing electrocardiogram
signal (ECG), the basis of this method is achieved through filtering singular values of the signal. The
advantage of this proposed method is its capability in enhancing the signal very well. The signals
under experiment are added by additive white noise with different levels of noise mixture and after
applying this method, the signals according to signal noise ratio (SNR) are evaluated, also time-
frequency spectrum are compared with each other. The efficiency of the proposed method is clear and
high enough in enhancing ECG.
