ABSTRACT
Most heart diseases are associated with and reflected by the sounds that the heart produces. Heart auscultation, defined as listening to the heart sound, has been a very important method for the early diagnosis of cardiac dysfunction. Traditional auscultation requires substantial clinical experience and good listening skills. The emergence of the electronic stethoscope has paved the way for a new field of computer-aided auscultation. This article provides an in-depth study of (1) the electronic stethoscope technology, and (2) the methodology for diagnosis of cardiac disorders based on computer-aided auscultation. The paper is based on a comprehensive review of (1) literature articles, (2) market (state-of-the-art) products, and (3) smartphone stethoscope apps. It covers in depth every key component of the computer-aided system with electronic stethoscope, from sensor design, front-end circuitry, denoising algorithm, heart sound segmentation, to the final machine learning techniques. Our intent is to provide an informative and illustrative presentation of the electronic stethoscope, which is valuable and beneficial to academics, researchers and engineers in the technical field, as well as to medical professionals to facilitate its use clinically. The paper provides the technological and medical basis for the development and commercialization of a real-time integrated heart sound detection, acquisition and quantification system.

Mentions: Currently this is no product offering for a truly specialized stethoscope tailored to the automatic heart disease diagnosis. Most of the products offer a wide range of generalist features for general auscultations. Nevertheless, thanks to the signal recording and transmitting capability offered by these products, the digital HS data can be recorded locally and transferred to a PC for visualization and further analysis. Some electronic stethoscopes can become portable by establishing connections to other handheld devices like mobile phone or wirelessly transmitting the sound signals to a remote processing unit through Bluetooth. Figure 12 shows an electronic stethoscope with a mobile phone [136] to view the HSs and send the sound recordings instantly for telemedicine applications.Figure 12
