Rheumatic Heart Disease Screening Based on Phonocardiogram [PDF]

open access: goldSensors, 2021
Rheumatic heart disease (RHD) is one of the most common causes of cardiovascular complications in developing countries. It is a heart valve disease that typically affects children. Impaired heart valves stop functioning properly, resulting in a turbulent

A Hardware-Software System for Accurate Segmentation of Phonocardiogram Signal. [PDF]

open access: goldJ Biomed Phys Eng, 2023
Background: Phonocardiogram (PCG) signal provides valuable information for diagnosing heart diseases. However, its applications in quantitative analyses of heart function are limited because the interpretation of this signal is difficult.

The utility of phonocardiograms in real-time remote cardiac auscultation using an internet-connected electronic stethoscope: Open-label randomized controlled pilot trial [PDF]

open access: greenDigital Health, 2023
Background We have shown classical cardiac auscultation was superior to remote auscultation. We developed a phonocardiogram system to visualize sounds in remote auscultation.

Phonocardiogram Signal Based Multi-Class Cardiac Diagnostic Decision Support System

open access: yesIEEE Access, 2021
A Phonocardiogram (PCG) signal represents murmurs and sounds signals made by vibrations caused for the period of a cardiac cycle. Acoustic wave generated through the beat of the cardiac cycle propagates through the chest wall.

Robust Denoising of Phonocardiogram Signals Using Time-Frequency Analysis and U-Nets

open access: yesIEEE Access, 2023
Cardiovascular diseases are the cause of many deaths worldwide every day. Automated cardiac auscultation is a promising diagnosis method; however, one of its main disadvantages is that it is prone to receiving too much noise during sound recording, which

Application of Acoustic Cardiography in Assessment of Cardiac Function in Horses with Atrial Fibrillation Before and After Cardioversion [PDF]

open access: yesAnimals
Left atrial mechanical dysfunction is common in horses following the treatment of atrial fibrillation (AF). This study aimed to evaluate the use of an acoustic cardiography monitor (Audicor®) in quantifying cardiac mechanical and hemodynamic function in ...

Rivero-Carvallo Sign in Bioprosthetic Tricuspid Valve Stenosis [PDF]

open access: yesJACC: Case Reports, 2023
In a case with bioprosthetic tricuspid stenosis, simultaneous phonocardiogram and Doppler recordings revealed that the louder diastolic rumble in inspiration (Rivero-Carvallo sign) is related to increased tricuspid gradient caused by less prominent ...

A multimodal parallel method for left ventricular dysfunction identification based on phonocardiogram and electrocardiogram signals synchronous analysis

open access: yesMathematical Biosciences and Engineering, 2022
Heart failure (HF) is widely acknowledged as the terminal stage of cardiac disease and represents a global clinical and public health problem. Left ventricular ejection fraction (LVEF) measured by echocardiography is an important indicator of HF ...
