    Area of Science:

    • Cardiology
    • Gastroenterology
    • Neurology

    Background:

    • Swallow syncope is a rare condition characterized by vasovagal responses triggered by swallowing.
    • It is often misdiagnosed due to its infrequent occurrence and varied presentations.
    • Underlying esophageal or cardiac abnormalities can predispose individuals to this condition.

    Observation:

    • Three distinct cases of swallow syncope are presented.
    • One case was associated with digitalis toxicity.
    • Two cases were linked to diffuse esophageal spasm.

    Findings:

    • Enhanced vagal tone during mastication and deglutition is the primary mechanism.
    • Esophageal motility disorders and cardiac conditions are significant contributing factors.

  • Diagnostic workup includes thorough patient history, esophageal manometry, and cardiac evaluation.

    • Implications:

    • Accurate diagnosis of swallow syncope is crucial for appropriate management.
    • Early identification and treatment can prevent recurrent syncopal episodes.
    • Understanding the underlying pathophysiology aids in developing targeted therapeutic interventions.
