    Area of Science:

    • Cardiology
    • Electrophysiology

    Background:

    • His bundle electrogram (HBE) combined with stimulation is valuable for diagnosing conduction disturbances, understanding arrhythmias, and evaluating the atrioventricular (A-V) conducting system.
    • Despite its utility, challenges persist in electrophysiologic interpretation and prognostic implications of HBE findings.

    Purpose of the Study:

    • To discuss the utility and limitations of His bundle electrogram.
    • To present data from 300 patients to illustrate key aspects of HBE interpretation and application.

    Main Methods:

    • Utilized His bundle electrogram recordings.
    • Incorporated electrophysiologic stimulation methods.
    • Analyzed data from a cohort of 300 patients.

    Main Results:

    • Demonstrated the diagnostic value of HBE in identifying conduction disturbances.
    • Highlighted the role of HBE in elucidating arrhythmia mechanisms.
    • Provided insights into the electrophysiologic properties of the A-V conducting system.
    • Identified specific areas of ambiguity and limitations in HBE interpretation.

    Conclusions:

    • His bundle electrogram is a powerful tool in clinical electrophysiology.
    • Further research and consensus are needed to address the remaining challenges in HBE interpretation and prognostic value.
    • The presented data offers practical insights for clinicians utilizing HBE.
