    Area of Science:

    • Cardiovascular Electrophysiology
    • Medical Instrumentation
    • Biomedical Engineering

    Context:

    • Epicardial mapping is crucial for understanding cardiac arrhythmias.
    • Current methods can be time-consuming and complex.
    • Accurate measurement of cardiac electrical intervals is essential.

    Purpose:

    • To report the development and application of a digital display automatic chronometer for epicardial mapping.
    • To describe the electronic processing of epicardial potentials.
    • To introduce a device that simplifies and shortens the mapping procedure.

    Summary:

    • A tripolar electrode records epicardial potentials, which are electronically processed (amplified, filtered, rectified, summed).
    • The device automatically calculates and displays the interval between a reference signal and cardiac potentials at an adjustable rate.
    • Incorporation of a delay function expands the apparatus's applicability.

    Impact:

    • Simplifies the complex procedure of epicardial mapping.
    • Reduces the time required for electrophysiological assessments.
    • Improves the efficiency and potentially the accuracy of diagnosing cardiac electrical abnormalities.
