Why the study?
Physiological noises such as ECG artifacts affect EEG signals and hinder accurate diagnosis, necessitating methods to detect and remove these noise components.
Does the Zero Phase Filtering method effectively remove ECG artifacts from EEG signals?
Population
EEG recordings from the MIT-BIH Polysomnography EEG dataset (specifically patient slp01b)
Comparison
Zero Phase Filtering method applied to regions… vs Raw EEG signal containing ECG noise
Design
Review
Key result
Applying Zero Phase Filtering to EEG regions corresponding to ECG QRS complexes successfully removed ECG noise while preserving the integrity of the remaining EEG signal, achieving a correlation coefficient of 0.989.

Does the Zero Phase Filtering method effectively remove ECG artifacts from EEG signals?
Zero Phase Filtering applied specifically to QRS complex regions effectively removes ECG artifacts from EEG signals while preserving essential brain signal data.
Sema Yıldırım (2025) conducted a review in ECG artifacts in EEG signals. Zero Phase Filtering (ZPF) based on QRS complex detection vs. Raw EEG signal with ECG noise was evaluated on Correlation between ZPF-filtered EEG signal and raw EEG signal. Applying Zero Phase Filtering to EEG regions corresponding to ECG QRS complexes successfully removed ECG noise while preserving the integrity of the remaining EEG signal, achieving a correlation coefficient of 0.989.
