Hypersensitive carotid sinus syndrome – MCQ – Answer

A cardioinhibitory response in hypersensitive carotid sinus syndrome, minimum duration of sinus pause required for diagnosis – Correct answer: c) Three seconds

By definition, cardioinhibitory response is a sinus pause of 3 seconds or more. Vasodepressor response requires a fall in systolic blood pressure of 50 mm Hg or more. It is checked by monitoring heart rate and blood pressure during pressure on the carotid sinus. But testing should not be done in those with a carotid bruit or history of cerebrovascular disease in view of risk of embolism of atherosclerotic from carotid arteries (artery to artery embolism).
