    Summary

    This study identifies re-entry phenomenon as the cause of a patient's heart rhythm disturbance. Withdrawing digoxin and Inderal resolved the issue, suggesting their role in prolonging A-V conduction.

    Area of Science:

    • Cardiology
    • Electrophysiology

    Background:

    • Understanding the mechanisms of cardiac rhythm disturbances is crucial for effective patient management.
    • Re-entry phenomena can cause various arrhythmias, necessitating detailed investigation.

    Observation:

    • A patient presented with a specific heart rhythm disturbance.
    • The disturbance was linked to a localized unidirectional block in the atrioventricular (A-V) junction.

    Findings:

    • The re-entry phenomenon was identified as the underlying mechanism for the patient's rhythm disturbance.
    • Predisposing factors, including digoxin and Inderal, were implicated for prolonging atrioventricular (A-V) conduction and facilitating reciprocal beats.
    • Temporary withdrawal of digoxin and Inderal led to the disappearance of the re-entry phenomenon.

    Implications:

    • This case highlights the importance of considering medication effects in the etiology of arrhythmias.
    • Management strategies involving medication adjustment can effectively resolve certain re-entrant arrhythmias.
    • Further research into drug-induced A-V conduction abnormalities is warranted.
