Integrated denoising steps for electrocardiogram signal / 医疗卫生装备

ABSTRACT

The ratio of signal-noise of the ECG(electrocardiogram) signal is low.In order to eliminate the noise in ECG,improve the performance of ECG monitors and the diagnosis efficiency of computer-aided system,various kinds of noise rejection methods have been proposed.Generally,maybe all of them are useful to the denoising in some certain,but not full.In this thesis,a series of denoising steps are introduced.As a result,a relatively original ECG waveform is detected.
