    This study introduces a compact device that analyzes electrocardiogram (ECG) R waves to measure interbeat intervals. The device classifies these intervals into eight categories, aiding in heart rate variability analysis.

    Area of Science:

    • Biomedical Engineering
    • Cardiovascular Technology
    • Medical Device Development

    Background:

    • Accurate measurement of heart rate variability is crucial for diagnosing cardiac conditions.
    • Existing methods for interbeat interval analysis can be complex or require specialized equipment.

    Purpose of the Study:

    • To describe a novel compact device for analyzing electrocardiogram (ECG) R waves.
    • To detail the device's capability in calculating, classifying, and storing interbeat interval durations.

    Main Methods:

    • The device detects the R wave from an ECG signal.
    • It calculates the duration of successive interbeat intervals.
    • Intervals are classified into eight distinct categories and counts are stored on an integrated circuit.
