    This study introduces a computer method for analyzing exercise electrocardiography (ECG) signals. The technique effectively removes exercise-induced noise, enabling precise analysis of cardiac electrical activity during rest and exertion.

    Area of Science:

    • Cardiology
    • Biomedical Engineering
    • Signal Processing

    Context:

    • Frank Vectorcardiography (VCG) is a valuable diagnostic tool.
    • Exercise stress tests can introduce electrical noise, complicating VCG analysis.
    • Accurate interpretation of VCG during exertion is crucial for diagnosing cardiac conditions.

    Purpose:

    • To present a novel computer method for analyzing Frank VCG signals.
    • To eliminate electrical noise from exercise-induced artifacts in VCG recordings.
    • To enable detailed pattern recognition and quantitative analysis of cardiac electrical activity.

    Summary:

    • A computer method analyzes Frank VCG recordings from rest and exertion.
    • Exercise noise is mitigated by averaging 8 complexes.
