Logistic Regression-HSMM-based Heart Sound Segmentation

Source: Physionet

The identification of the exact positions of the first and second heart sounds within a phonocardiogram (PCG), or heart sound segmentation, is an essential step in the automatic analysis of heart sound recordings, allowing for the classification of …

Generalized Multiscale Entropy Analysis

Source: Physionet

The method of generalized multiscale entropy (GMSE) analysis is useful for investigating complexity in physiologic signals and other series that have correlations at multiple (time) scales. It represents a generalization of the original method of mu…

ECGPUWAVE

Source: Physionet

ecgpuwave analyses an ECG signal from the specified record, detecting the QRS complexes and locating the beginning, peak, and end of the P, QRS, and ST-T waveforms. The output of ecgpuwave is written as a standard WFDB-format annotation file associa…

Measurement of Global Electrical Heterogeneity

Source: Physionet

The Global Electrical Heterogeneity (GEH) concept is based on the theory of Wilson’s electrical gradient vector, which characterizes the degree of heterogeneity of the total recovery time across the ventricles.

Multiscale Poincare Plots

Source: Physionet

Poincaré delay maps are widely used in the analysis of cardiac interbeat interval (RR) dynamics. To facilitate visualization of the structure of these complex time series, we introduced a methodology called multiscale Poincaré (MSP) pl…
