Swallowing syncope. A case report

S Golf

    Acta Medica Scandinavica
    |January 1, 1977

    Summary
    This summary is machine-generated.

    A rare heart condition caused fainting and seizures during meals for 13 years. Ambulatory ECG revealed intermittent atrioventricular (AV) block during swallowing, resolved by pacemaker implantation.

    Area of Science:

    • Cardiology
    • Neurology
    • Gastroenterology

    Background:

    • Syncope and seizures during meals are rare symptoms.
    • Misdiagnosis can lead to prolonged suffering and delayed treatment.

    Observation:

    • A previously healthy male presented with recurrent syncopes and convulsions exclusively during meals.
    • Extensive gastroenterologic, neurologic, and cardiologic evaluations failed to identify the cause, leading to a psychiatric misdiagnosis for 13 years.

    Findings:

    • Ambulatory electrocardiogram (ECG) monitoring identified intermittent 2nd-degree atrioventricular (AV) block specifically occurring during the act of swallowing.
    • This previously unrecognized trigger for cardiac arrhythmia was the underlying cause of the patient's symptoms.

    Implications:

    Related Experiment Videos

    • Highlights the importance of considering cardiac causes for unexplained syncopal and convulsive episodes, even with negative initial workups.
    • Demonstrates the diagnostic utility of prolonged ambulatory ECG monitoring in identifying transient arrhythmias.
    • Pacemaker implantation effectively resolved the symptoms, underscoring the efficacy of appropriate intervention for this specific type of AV block.
