Enhanced Electronic Stethoscope

, 2010
In this paper we present a new design of a modified stethoscope. The main objective is to enable the early detection of heart defects in newborn infants. The design uses signal processing to enable the improvement of detection. The design was simulated and the results show that the device would make detection of defects much more precise and efficient.

Acoustic Cardiography Captures Stress-Dependent Ventricular Dysfunction and Distinguishes Heart Failure Phenotypes in a Porcine Model

Biomedicines
Background: Heart failure with preserved ejection fraction (HFpEF) is a heterogeneous syndrome requiring invasive and/or exercise stress testing for diagnosis, in contrast with the homogeneous nature of HF with reduced EF (HFrEF).

An Effective Respiratory Sound Endpoint Detection for Electronic Stethoscope Based on Machine Learning

IET Signal Processing
Compared to human speech and multimedia audio, the amplitude of lung respiratory sounds is extremely weak, with minimal differences between the respiratory sounds of various lung diseases. Traditional methods, such as Mel-frequency cepstral coefficients (

Embedding a multichannel environmental noise cancellation algorithm into an electronic stethoscope

, 2011
The paper describes a multichannel adaptive algorithm for the enhancement of cardiac sounds with respect to environmental noise. It combines sounds acquired from a couple of microphones to reconstruct the transfer function of a stethoscope head and its ...

A Wireless Electronic Esophageal Stethoscope for Continuous Monitoring of Cardiovascular and Respiratory Systems during Anaesthesia

Journal of Biomedical Physics and Engineering, 2017
Background: The basic requirements for monitoring anesthetized patients during surgery are assessing cardiac and respiratory function. Esophageal stethoscopes have been developed for this purpose, but these devices may not provide clear heart and lung
