摘　　要：结合模板匹配和改进的导数阈值法,提出了一种QRS波群实时检测方法CT2(combination method of template matching and improved derivative threshold)。首先,预采集一段ECG信号,使用高斯函数构造QRS模板;然后将实时采集的ECG信号使用CT2检测R波位置。为了比较算法检测精度和效率,使用CT2和基于小波模极大值的方法进行了对比。结果表明,CT2检测精度与基于小波模极大值的方法相当,但运算时间大大缩短,适于实时检测。A QRS detection method CT2 was proposed by combining template matching with improved derivative threshold method.Firstly,a QRS template was constructed using Gaussian function according to ECG signals.Secondly,R wave detection was implemented using CT2.The accuracy and efficiency of CT2 and algorithm based on wavelet transform modulus maxima were compared.The results show that the accuracy equals whereas the CT2 method greatly shortens operation time thus it＇s suitable for real-time use.
