Novel phonocardiography system for heartbeat detection from various locations [PDF]
Scientific Reports, 2023 The paper presents evaluation of the proposed phonocardiography (PCG) measurement system designed primarily for heartbeat detection to estimate heart rate (HR). Typically, HR estimation is performed using electrocardiography (ECG) or pulse wave as one of

Use of proposed systolic and myocardial performance indices derived from simultaneous ECG and PCG recordings to assess cardiac function in healthy Beagles [PDF]
Veterinary World, 2022 Background and Aim: Cardiac time intervals (CTIs) can provide important information on the electrical and mechanical properties of the heart. We hypothesized that cardiac function can be described using the combined power of electrocardiography (ECG) and

Intracardiac Phonocardiography in Man [PDF]
Circulation, 1957 This paper describes a new method for the detection of sound from within the heart in man. It employs the technic and equipment of underwater listening developed and used by the Navy in antisubmarine warfare. Records are shown to illustrate the localization of heart sound production to an extent not possible by phonocardiograms from the chest wall. The

A Novel Method for ECG-Free Heart Sound Segmentation in Patients with Severe Aortic Valve Disease [PDF]
SensorsSevere aortic valve diseases (AVD) cause changes in heart sounds, making phonocardiogram (PCG) analyses challenging. This study presents a novel method for segmenting heart sounds without relying on an electrocardiogram (ECG), specifically targeting ...

Wavelet filtering of fetal phonocardiography: A comparative analysis
Mathematical Biosciences and Engineering, 2019 Fetal heart rate (FHR) monitoring can serve as a benchmark to identify high-risk fetuses. Fetal phonocardiogram (FPCG) is the recording of the fetal heart sounds (FHS) by means of a small acoustic sensor placed on maternal abdomen.

A Wavelet Transform-Based Neural Network Denoising Algorithm for Mobile Phonocardiography
Sensors, 2019 Cardiovascular pathologies cause 23.5% of human deaths, worldwide. An auto-diagnostic system monitoring heart activity, which can identify the early symptoms of cardiac illnesses, might reduce the death rate caused by these problems.
