摘　　要：对QRS波群快速、准确定位是心电信号自动检测和分析的关键,其前提条件是消除心电信号中的各种噪声干扰;针对提高QRS波群检测算法的抗噪性能,提出了一种基于经验模态分解方法和平稳小波变换相结合的QRS波检测方法;该方法对QRS波检测准确率高、定位精度好。The rapid and accurate location of ECG signal of QRS complex is the key to the automatic detection and analysis of ECG signal. It is a prerequisite that efficiently eliminating the interruption of noises in ECG signal to accurately detect various characteristic waves. In order to improve the anti-noise performance of QRS detection algorithm,a QRS detection scheme based on EMD and wavelet transform is proposed in this paper. The algorithm realized a better detection and positioning accuracy.
