摘要
利用M arr小波特有的时频特性,采用离散小波变换的直接算法,对心电信号QRS波群进行识别,经M IT/B IH心电数据库的检测验证,即使有严重的噪声信号干扰,也能精确定位R波,其正确率为99.7%,能准确地识别QRS时限,实时地识别R波和QRS时限。可用于心电信号实时处理。
Using the special time-frequency properties of Marr wavelet function and the direct algorithm of discrete wavelet transforms, the QRS complexes are identified from ECG signal. By using the MIT/BIH （Massachusetts Institute of Technology/Boston＇s Beth Israel Hospital） arrhythmia database and the ap-plications in clinic, the precise detection method can be used to accurately detect and precisely localize the QRS complex in the ECG signal with the serious noise.
