| 摘 要： | 利用小波变换能处理多尺度多分辨的特点,将心电信号进行多尺度分解,把不同频带的信号显现在小波分解各个尺度上。特征尺度上准确定位QRS波及T波的起始点,从而获得人体心电信号(ECG)中的QT间值。人体心电信号具有非平稳性和干扰多的特点,利用小波分析对心电信号进行处理能够获得精确的QT间值,为临床诊断提供了更加准确的依据。 |
| 关 键 词： | 小波分析 人体心电信号 QRS波 QT间期 |

| Abstract: | This paper shows how to acquire exact value of QT interval of ECG using wavelet analysis.ECG signals of different frequencies were extracted by multi-scales decomposition.Since QRS wave and T wave can be identified accurately by characteristic scales,QT interval can be captured exactly.The proposed method is especially suitable for ECG signals because these signals are unbalanced and noisy.When applied to real data,the method provides more accurate diagnostic information. |
| Keywords: | wavelet analysis ECG signal QRS wave QT interval |
