| 摘 要： | 采用二进小波变换与斜率和幅度相结合的方法，对小鼠QRS复合波进行检测。根据小鼠QRS复合波的特点，采用Daubechics小波为母函烽，按照ECG的频谱特点选用尺度因子，对有噪声污染和形态变异的QRS复合波进行了检测。结果表明：小波变换对小鼠QRS复合波的检测是一种有效的方法。 |

| Abstract: | In this paper,we describe a rat's QRS complex detector based on the dyadic wavelet transform which associate with the slope and range.A Daubechics mother function is used that is suitable for QRS detection.The scales of this wavelet are chosen based on the spectral characteristics of the electrocardiogram(ECG)signal.The rat's QRS complexes are detected success-fully which are time-varying morphology and noisy.The results show that wavelet transform is a efficient method for the rat's QRS complexes detecting. |
| Keywords: | dyadic wavelet transform detection of QRS complex scale |
