PhonoSys: Mobile Phonocardiography Diagnostic System for Newborns

EAI Endorsed Transactions on Mobile Communications and Applications, 2016
Heart murmurs have been found to be a life threatening condition for the newborns who are born with cardiac abnormalities. The first sign of pathological changes of heart valves appears in phonocardiogram which contains very useful information about ...

Algorithm for heart rate extraction in a novel wearable acoustic sensor. [PDF]

, 2015
Phonocardiography is a widely used method of listening to the heart sounds and indicating the presence of cardiac abnormalities. Each heart cycle consists of two major sounds - S1 and S2 - that can be used to determine the heart rate.

Learning technology in health professions education: Realising an (un)imagined future

Medical Education, Volume 58, Issue 1, Page 36-46, January 2024.
Abstract Context Technology is being introduced, used and studied in almost all areas of health professions education (HPE), often with a claim of making HPE better in one way or another. However, it remains unclear if technology has driven real change in HPE.

A COMPARISON OF METHODS USING STRAIN GAUGES TO MONITOR PHYSIOLOGICAL MOVEMENTS ON A HOSPITAL BED [PDF]

, 2017
Two methods which are suitable to monitor the small movements of the patient in a horizontal position on the bed are compared. The methods use sensors based on strain gauge bridges configured to measure the torsion deformation and sensors based on strain

Time-frequency scaling transformation of the phonocardiogram based of the matching pursuit method.

, 1998
International audienceA time-frequency scaling transformation based on the matching pursuit (MP) method is developed for the phonocardiogram (PCG). The MP method decomposes a signal into a series of time-frequency atoms by using an iterative process. The

Cardiac Multi-Frequency Vibration Signal Sensor Module and Feature Extraction Method Based on Vibration Modeling

Sensors
Cardiovascular diseases pose a long-term risk to human health. This study focuses on the rich-spectrum mechanical vibrations generated during cardiac activity. By combining Fourier series theory, we propose a multi-frequency vibration model for the heart,

Correlation Analysis in a Pulse Wave Velocity Evaluation [PDF]

, 2004
In this paper, methods for a time delay evaluation of phonocardiographic (PCG) signals are presented to estimate a pulse wave velocity (PWV) in a cardiovascular system of a human body, especially in arterial segments of an arterial tree selected.
