基于差分方法的QRS波检测

QRS Detection Based on Difference Method

我们提出了一种基于差分方法的QRS波检测方法。该方法通过计算心电信号的差分函数,消除或减弱P波T波以及其它干扰信号对QRS波检测的影响,解决了传统检测方法检测准确率低和小波检测算法复杂,计算量大的问题。在对多组来自MIT-BIH数据库数据的实验结果表明,该方法对于各种病态波形具有很好的适应性。在我们研制的"十二导心电图PC系统"中,该方法已得到了临床应用,检测准确率达到99%以上。

A difference method for detection of QRS is proposed in this paper. By calculating the difference function of the Electrocardiogram(ECG), the method can eliminate or weaken the impact of the P wave, T wave and other interference signals onto the detection of QRS. It can solve the problem of low detection accuracy yielded by the traditional method, and can solve the problem of heavily loaded computation caused by the complicated algorithm of the wavelet method. Experiments using data from the MIT-BIH arrhyth...
