Survey of Different Methodologies Used in Phonocardiogram Signal Analysis

Abstract

Heart sounds give us information about the state of the heart. Heart diseases can be detected at an earlier stage by analyzing the heart sounds. In this paper, detailed discussion of various methodologies that have been used earlier to analyze the heart sounds has been carried out. Comparison has been done on the basis of methodology used and the performance achieved.
