Abstract: Carotid sinus hypersensitivity is common in elderly patients. Baroreceptor function generally decreases with age but some people experience hypersensitive carotid baroreflexes. In such individuals, even mild stimulation to the neck results in profound bradycardia and hypotension. In this case, CSH was elicited during internal jugular venous cannulation which is a common procedure in cardiac surgery. Knowledge about CSH can help us to take appropriate precautions in perioperative period and manage cardiac instability arising from this reflex.

Keywords: Carotid sinus hypersensitivity, baroreceptor, bradycardia, hypotension, internal jugular vein, syncope, atrio-ventricular pacing.
