Monitoring Cardiac Stress Using Features Extracted From S 1 Heart Sounds

Acoustic heart sounds are known to provide a powerful tool for providing cardiac activity. Heart sound contains significant information on the mechanical activity of heart. This paper presents a method for the analysis of cardiac monitoring. The proposed study involves analysis of certain morphological features of the acoustic signals that are associated with physiological changes of heart with a trained network. The study shows that the proposed features vary significantly during cardiac stress. KeywordsS1 heart sounds, signal transformations, feature extraction
