    Summary

    This study introduces a computer-based method to reduce electrocardiogram (EKG) artifact in electroencephalogram (EEG) recordings. The technique is particularly useful for EEG data that uses non-cephalic reference electrodes.

    Area of Science:

    • Neuroscience
    • Biomedical Engineering
    • Signal Processing

    Background:

    • Clinical electroencephalogram (EEG) recordings are susceptible to artifacts.
    • Electrocardiogram (EKG) artifact is a common issue, especially with non-cephalic reference electrodes.
    • Minimizing EKG artifact is crucial for accurate EEG analysis.

    Purpose of the Study:

    • To describe a novel computer-based technique for real-time subtraction of EKG artifact.
    • To enhance the quality of clinical EEG recordings.

    Main Methods:

    • Development of a computer-based algorithm for on-line, real-time artifact subtraction.
    • Implementation of the subtraction technique specifically for EEG data with non-cephalic references.

    Main Results:
