Distribution of selected features with significantly different values among all types of heartbeats confirmed by statistical analysis (p < 0.05): (a) QRS complex duration (QRSD), (b) area under segment selected as a part of ECG 60 ms before to 60 ms after R peak position (p60), (c) mean value of QRS in Wigner-Ville distribution within frequency range 0–500 Hz (WVm), (d) mean of continuous wavelet representation of QRS complex (WTm).
