Heart energy signature spectrogram for cardiovascular diagnosis
BioMedical Engineering OnLine, 2007 A new method and application is proposed to characterize intensity and pitch of human heart sounds and murmurs. Using recorded heart sounds from the library of one of the authors, a visual map of heart sound energy was established.

A framework for automatic heart sound analysis without segmentation
BioMedical Engineering OnLine, 2011 Background A new framework for heart sound analysis is proposed. One of the most difficult processes in heart sound analysis is segmentation, due to interference form murmurs.

Computerized heart sounds analysis [PDF]
Computers in Biology and Medicine, 2008 This paper is concerned with a synthesis study of the fast Fourier transform (FFT), the short-time Fourier transform (STFT), the Wigner distribution (WD) and the wavelet transform (WT) in analysing the phonocardiogram signal (PCG). It is shown that these transforms provide enough features of the PCG signals that will help clinics to obtain qualitative ...

The Assessment of Stent Effectiveness Using a Wearable Beamforming MEMS Microphone Array System
IEEE Journal of Translational Engineering in Health and Medicine, 2016 Studies involving turbulent flow have been carried out in many parts of the cardiovascular system, and it has been widely reported that turbulence related to stenosis (narrowing) of arteries creates audible sounds, which may be analyzed to yield ...
