Abstract

To the Editor: The Images in Clinical Medicine in the July 1 issue1 intrigued me. I am uncertain whether the hemodynamic reaction shown represents syncope mediated by the neurocardiogenic (Bezold-Jarisch) reflex or carotid-sinus hypersensitivity with only a vasodepressor component. Generally, bradycardia is expected in neurocardiogenic syncope, which is thought to be mediated by vagal afferent and efferent fibers2,3. Conversely, carotid-sinus hypersensitivity mediated by glossopharyngeal afferent fibers occurs without bradycardia in a pure vasodepressor reaction4. Given the patient's history of metastatic cancer of the neck, carotid-sinus hypersensitivity seems to be a strong candidate for having produced the illustrated…
