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.
