摘要
随着医学技术的不断进步,人们可以通过对心电信号的研究来诊断心脏病的严重程度及各种症状,但如何得到一个无噪声的心电信号,即对心电信号的去噪声已成为医学上越来越关注的研究热点。详细介绍了小波变换原理,通过小波变换原理对心电信号阈值进行去噪,由此得到一个纯净的心电信号,为诊断心脏病提供了一个新的方法。
With the continuous progress of medical technology,people can diagnose the severity and symptoms of heart disease through the research on the ECG signal,but how to get a non-noise ECG signal,namely the denoising of ECG signals has become a hot research topic in medical science.This paper introduces the principle of wavelet transform in detail,denoises the threshold of ECG signal by the principle of wavelet transform,and thus obtains a pure ECG signal,to provide a new method for diagnosing heart disease.
