Function Documentation

ECG_feat_extr()

function ECG_feat_extr	(	in	ECGSignal,
		in	varargin
	)

Parameters

ECGSignal

the ECG signal (already subtracted from one lead)

varargin

you can choose which features to extract default or no input will result in extracting all the features (see feature Extractor) featues names include: meanIBI: mean interbeat interval HRV: heart rate variability (deviation of IBI) MSE: Multi-Scale Entropy at 5 levels 1-5 (5 features) sp0001: Spectral power 0-0.1Hz, sp0102: Spectral power 0.1-0.2Hz, sp0203: Spectral power 0.2-0.3Hz, sp0304: Spectral power 0.3-0.4Hz, energyRatio: Spectral energy ratio between f<0.08Hz/f>0.15Hz and f<5.0Hz tachogram_LF: Low frequency spectral power in tachogram (HRV) [0.01-0.08Hz] tachogram_MF: Medium frequency spectral power in tachogram (HRV) [0.08-0.15Hz] tachogram_HF: High frequency spectral power in tachogram (HRV) [0.15-0.5Hz] tachogram_energy_ratio: Energy ratio for tachogram spectral content (MF/(LF+HF))

Return values

ECG_features	vector of features among the following features
ECG_feats_names	the names of the features is the same order than in 'ECG_features'
Bulk	if the input to the function is a Bulk than the Bulk is returned with the updated ECG signal, including IBI. Otherwise NaN is returned
