    This study introduces a new test to classify sinus node function by examining heart rate recovery after autonomic blockade. The test differentiates normal and pathological cases based on intrinsic heart rate and post-pacing parameters.

    Area of Science:

    • Cardiology
    • Electrophysiology
    • Autonomic Nervous System

    Background:

    • The autonomic nervous system significantly influences cardiac function.
    • Understanding sinus node function is crucial for diagnosing arrhythmias.
    • Existing methods may not fully capture pathological sinus node behavior.

    Purpose of the Study:

    • To develop and validate a novel electrophysiological test for assessing sinus node function.
    • To differentiate between normal and pathological sinus node responses.
    • To establish a physiopathological classification of sinus node behavior.

    Main Methods:

    • Autonomic blockade using atropine and propranolol.
    • Determination of intrinsic heart rate (IHR).
    • Rapid atrial pacing (RAP) with analysis of primary and secondary post-pacing parameters.

    Main Results:

    • Normal and pathological cases were distinguished based on IHR.
    • Heart rate recovery in the secondary phase (2-10 beats) showed exponential characteristics in normal cases.
    • Electrophysiological anomalies were identified in both primary and secondary phases, including prolonged recovery time and failure to return to baseline cycle length.

    Conclusions:

    • The new test effectively differentiates normal and pathological sinus node function.
    • Identified anomalies provide insights into the physiopathology of sinus node dysfunction.
    • This method allows for a refined physiopathological classification of sinus node behavior.
