Heart Sound Classification based on Residual Shrinkage Networks

2022 44th Annual International Conference of the IEEE Engineering in Medicine & Biology Society (EMBC), 2022
Heart sound classification is one of the non-invasive methods for early detection of the cardiovascular diseases (CVDs), the leading cause for deaths. In recent years, Computer Audition (CA) technology has become increasingly sophisticated, auxiliary diagnosis technology of heart disease based on CA has become a popular research area.

Processing of prosthetic heart valve sounds for classification

Proceedings of IEEE Symposium on Computer-Based Medical Systems (CBMS), 2002
People with serious heart conditions have had their expected life span extended considerably with the development of the prosthetic heart valve especially with the great strides made in valve design. Even though the designs are extremely reliable, the valves are mechanical and operating continuously over a long period, therefore, structural failures ...

Classification of Heart Sounds Using MFCC and CNN

2021
An excellent heart sound classification system can be used as a good method to complete the daily heart sound detection under the condition of low cost and high efficiency, which is convenient to detect problems in the early stage of heart disease, and at the same time can alleviate the problem of medical staff shortage.

Heart sound classification using the SNMFNet classifier

Physiological Measurement, 2019
Abstract Objective : Heart sound classification still suffers from the challenges involved in achieving high accuracy in the case of small samples. Dimension reduction attempts to extract low-dimensional features with more discriminability from high-dimensional spaces or raw data, and is ...

Classification of mechanical prosthetic heart valve sounds

International Journal of Computational Science and Engineering, 2013
Heart sounds of patients are usually used for analysis by cardiologists for the purpose of early detection of various heart diseases. In this paper, Hilbert-Huang transform HHT is applied to analyse five different kinds of mechanical prosthetic heart valve sounds, and an HHT-based feature extraction procedure is also developed to classify these five ...

A novel heart-mobile interface for detection and classification of heart sounds

Biomedical Signal Processing and Control, 2018
Abstract Diagnosis of heart disease requires that a medical practitioner investigate heart auscultations for irregular sounds, followed by echocardiography and electrocardiography tests. These expensive tests also require specialized technicians to operate.

Classification of normal and abnormal heart sounds

2017 Fourth International Conference on Advances in Biomedical Engineering (ICABME), 2017
Heart hemodynamic status and detection of a cardiovascular disease can be evaluated by analyzing and visualizing the heart waveform through graphs called the Phonocardiogram (PCG). The normal sounds of the heart generate signals that are in the audible frequency range of the human ear.

Multimodal classification of heart sounds attributes

2014 Pan American Health Care Exchanges (PAHCE), 2014
Pollution and associated negative impacts on human health is one of the major concerns of the World Health Organization and healthcare providers. Current interests focus on particles suspended in air known as PM 10 which significantly contribute to increased prevalence of heart disease.

Classification of heart sounds using an artificial neural network

Pattern Recognition Letters, 2003
A novel method is presented for the classification of heart sounds (HSs). Wavelet transform is applied to a window of two periods of HSs. Two analyses are realized for the signals in the window: segmentation of the first and second HSs, and extraction of the features.After the segmentation, feature vectors are formed by using the wavelet detail ...
