Izvirni znanstveni članek
Oznake: phase portrait;auscultation;mitral valve dysfunction;heart murmur;nonlinear time series analysis;
The manuscript elucidates the potential of phase portrait, fast Fourier transform, wavelet, and time-series analyses of the heart murmur (HM) of normal (healthy) and mitral regurgitation (MR) in the diagnosis of valve-related cardiovascular diseases. The temporal evolution study of phase portrait an ...

Oznake: phase portrait;time series;feature extraction;pleural rub;
This paper proposes a novel surrogate method of classification of breath sound signals for auscultation through the principal component analysis (PCA), extracting the features of a phase portrait. The nonlinear parameters of the phase portrait like the Lyapunov exponent, the sample entropy, the fr ...
