Clinical Cardiology, Volume 47, Issue 11, November 2024.A total of 204 patients and 49 features were collected. After splitting the population into training and test sets according to a ratio of 7:3, the LASSO and logistic regression was used to select the final five factors for a nomogram. The AUC for the nomogram model is 0.945, while the AUC for the echocardiographic parameters combined with NT‐proBNP in

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 ...

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.

Imaging of the heart with phonocardiography
bams, 2013 Abstract This paper focuses on techniques of phonocardiographic image registration. Simultaneous measurements of sound wave amplitudes from above the chest of a healthy person were performed by means of piezoelectric microphones. The location of the source of sound waves can be determined by implementing the size of the amplitudes. Sound

An Attempt on the Intracardiac Phonocardiography
The Tohoku Journal of Experimental Medicine, 1953 The intracardiac phonocardiography, in the meaning of the prototype of the heart sounds, was obtained by means of a condenser microphone using the body as one pole. The authors take this opportunity to express their sincere gratitude to Mr. Tadashi Fukuda for technical assistance and to Assist. Prof. Tadao Takahashi for reviewing the manuscript.
