Carotid Sinus Syndrome: What Is the Clinical Relevance of the Vasodepressor Component and How to Manage It?

  • C. Menozzi

Carotid sinus syndrome is diagnosed in patients with syncope who are found to have an hyperactive carotid sinus reflex to the carotid sinus massage test and a negative work-up. Hyperactive carotid sinus reflex is present if the carotid sinus massage produces asystole exceeding 3 s (a cardioinhibitory response) or a reduction in systolic blood pressure exceeding 50 mmHg (a vasodepressor response). These limits were chosen by Franke [1] among a large population of healthy subjects and patients with various diseases. They have been accepted widely even if they represent a workable compromise since an asystolic pause of 3 seconds and a decrease of blood pressure of 50 mmHg can also be observed in subjects without syncope. The reproduction of spontaneous symptoms during the carotid sinus massage seems to add specificity to the definition of the syndrome.
