Isolate two kinds of cardiac sinoatrial node field potentials by using wavelet analysis

Data got from cardiac electrophysiological experiment in this paper indicated that the sinoatrial node field potential was overlapped by two kinds of different signals. The two signals had totally different conductive characteristics. The traditional medical method could not separate these two signals. It brought great inconvenience to cardiac electrophysiological study. In order to solve this problem, we used wavelet transform to analyze sinoatrial node field potential in this paper. The results showed that wavelet analysis could separate the two kinds of field potentials effectively. The data processing used in this paper provided an effective method for medical researchers to process the experimental data of electrophysiological.
