An ECG waves separation technique based on mathematical morphology is suggested and discussed in this paper. Without detection of QRS complexes, the QRS complexes can be eliminated by series morphological operations. Then the start points and end points of P-wave and T-wave can be decided and the waves of ECG are separated qualitatively and quantitatively. The results of qualitative separations are rather satisfied and the SDs of quantitative separation results are not very large. Also, ECG signals are filtered and baseline is normalized by morphological method.
