Automated Detection and Removal of Cardiac and Pulse Interferences from Neonatal EEG Signals.

Sensors (Basel) 2021 Sep 23;21(19). Epub 2021 Sep 23.

Behavioral Imaging and Neural Dynamics Center, G. d'Annunzio University of Chieti-Pescara, 66100 Chieti, Italy.

Electrical cardiac and pulsatile interference is very difficult to remove from electroencephalographic (EEG) signals, especially if recorded in neonates, for which a small number of EEG channels is used. Several methods were proposed, including Blind Source Separation (BSS) methods that required the use of artificial cardiac-related signals to improve the separation of artefactual components. To optimize the separation of cardiac-related artefactual components, we propose a method based on Independent Component Analysis (ICA) that exploits specific features of the real electrocardiographic (ECG) signals that were simultaneously recorded with the neonatal EEG.
