小波变换在心电图R波检测中的应用

The Application of Wavelet Transform in Electrocardiogram R Wave Detection

介绍了一种新颖的信号处理方法－小波变换．利用三阶样条小波分析了信号的奇异点与其小波变换的关系，并通过ＥＣＧ信号的小波变换，分析了小波变换的抗干扰能力．

This article introduces a new signal processing method-wavelet transform.We make use of third-order spline wavelet to analyse the relationship between the signal sigularity and its walelet transform,and analyse the ability of anti-disturbance by the wavelet transform of ECG signal.Finally we develop a method of QRS detection based on wavelet transform.
