摘要：

In this paper an improved algorithm for segmentation of phonocardiographic signal has been proposed. The algorithm is based on the use of spectrogram, which is calculated from the high-pass filtered phonocardiogram. The spectrogram is quantified to two values and projected to time axis to have the boundaries of heart events. Conclusion: more exact segmentation boundaries of the heart sound signal could be achieved and the performance of further analysis is improved.
