    Area of Science:

    • Cardiology
    • Biomedical Engineering
    • Physiology

    Background:

    • Ballistocardiography (BCG) is a non-invasive technique to assess cardiovascular function.
    • Existing BCG classifications have limitations in differentiating pathological changes.
    • Accurate classification is crucial for understanding cardiovascular dynamics.

    Purpose of the Study:

    • To propose an improved classification system for ballistocardiographic changes.
    • To enhance the differentiation between cardiovascular and extracardial factors in pathological BCG.
    • To maintain consistency with existing nomenclature to minimize errors.

    Main Methods:

    • Critical analysis of frequently used ballistocardiographic classifications.
    • Development of a new classification incorporating Brown's scale, wave/segment configurations, amplitudes, and time dependencies.
    • Validation of the proposed classification's ability to differentiate first-degree pathological changes.

    Main Results:

    • An improved classification for ballistocardiographic changes is proposed.
    • The classification integrates pathological degree, wave characteristics, and temporal factors.
    • Enhanced differentiation of first-degree pathological changes into cardiovascular and extracardial origins is achieved.

    Conclusions:

    • The proposed classification offers a more refined approach to interpreting ballistocardiographic data.
    • It improves the distinction between cardiovascular and extracardial causes of abnormal BCG patterns.
    • The system's adherence to existing symbols facilitates adoption and reduces potential errors.
