    Vasodepressor carotid sinus syncope is rare, with few treatment options. A combination of ephedrine and fludrocortisone significantly improved symptoms in one patient, offering a potential therapeutic avenue.

    Area of Science:

    • Cardiology
    • Neurology
    • Otolaryngology

    Background:

    • Vasodepressor carotid sinus syncope is infrequently reported, lacking established treatment protocols.
    • This type of syncope is distinct from the more common cardioinhibitory form.
    • A patient with a history of laryngeal tumor surgery and radiotherapy presented with recurrent syncope.

    Observation:

    • A 58-year-old male patient experienced recurrent syncope, characterized by hypotension, neck pain, dizziness, and bradycardia, following laryngeal cancer treatment.
    • Initial treatment with a temporary pacemaker was ineffective in preventing syncopal episodes.

    Findings:

    • Pharmacological intervention with ephedrine (a vasoconstrictor) and fludrocortisone (a plasma volume expander) led to substantial symptom improvement.

  • While drug therapy showed efficacy, it did not completely eliminate the syncopal episodes, indicating a need for optimized treatment protocols.

    • Implications:

    • This case highlights the potential benefit of combined vasoconstrictor and plasma volume expander therapy for vasodepressor carotid sinus syncope.
    • Further investigation into combined drug regimens may offer a viable treatment alternative for patients unresponsive to conventional therapies.
