    Arfonad administration caused severe, reversible electrocardiographic abnormalities in a patient with acute aortic dissection. Close monitoring is advised, especially for patients with heart conditions or those on catecholamine-depleting drugs.

    Area of Science:

    • Cardiology
    • Pharmacology

    Background:

    • A patient with type III acute aortic dissection, previously treated with alpha-methyl-dopa, received Arfonad.
    • The patient developed severe and reversible electrocardiographic abnormalities.

    Observation:

    • The observed electrocardiographic changes included first-degree atrioventricular block, left bundle branch block, and ventricular fibrillation.
    • Other potential causes for these cardiac events were ruled out through clinical and laboratory assessments.

    Findings:

    • Arfonad administration was directly linked to the induction of significant electrocardiographic abnormalities.
    • The precise mechanism underlying Arfonad's effect on cardiac conduction in this context remains unclear despite literature review.

    Implications:

    • Strict electrocardiographic monitoring is recommended during Arfonad administration.
    • Particular caution is advised for patients with pre-existing cardiac conduction defects or those on catecholamine-depleting medications like alpha-methyl-dopa.
