Classification of the heart sounds via artificial neural network
International Journal of Reasoning-based Intelligent Systems, 2010Auscultation with stethoscope is a preferential method that the doctors use in order to differentiate normal cardiac systems from the abnormal ones that come out. On the other hand, the method of auscultation with stethoscope requires medical expert experience and careful listening.

An expert system approach for classification of heart sounds and murmurs
Proceedings of the Sixth International Symposium on Signal Processing and its Applications (Cat.No.01EX467), 2002The various types of heart valvular problems can be classified from the auscultation of heart sounds and murmurs that only requires the use of the stethoscope. To discriminate the various heart sounds and murmurs, the signal parameters are estimated using the instantaneous energy and frequency estimation (IEFE) technique.

Heart sounds classification using motif based segmentation
Proceedings of the 18th International Database Engineering & Applications Symposium on - IDEAS '14, 2014In this paper we describe an algorithm for heart sound classification (classes Normal, Murmur and Extrasystole) based on the discretization of sound signals using the SAX (Symbolic Aggregate Approximation) representation. The general strategy is to automatically discover relevant top frequent motifs and relate them with the occurrence of systolic (S1 ...

Effect of early and late fusion on heart sound classification
2018 26th Signal Processing and Communications Applications Conference (SIU), 2018Heart sounds; together with important clues in the evaluation of heart diseases, is a guide for advanced diagnostic examination and is used for the early diagnosis of cardiovascular diseases. Auscultation of heart sounds is an important part of the physical examination and allows understanding of many pathological heart diseases such as heart valve ...

Supervised threshold-based heart sound classification algorithm
Physiological Measurement, 2018Deep classification networks have been one of the predominant methods for classifying heart sound recordings. To satisfy their demand for sample size, the most commonly used method for data augmentation is that which divides each heart sound instance into a number of segments, with each segment labelled as the same category as its origin and used as a ...

Classification of prosthetic heart valve sounds: A parametric approach
The Journal of the Acoustical Society of America, 1995People with heart problems have had their lives extended considerably with the development of the prosthetic heart valve. Great strides have been made in the development of the valves through the use of improved materials as well as efficient mechanical designs.
