Carotid sinus massage is a clinical maneuver used to diagnose and sometimes treat certain types of cardiac arrhythmias, particularly supraventricular tachycardia (SVT). This technique involves gently massaging the carotid sinus, an area located in the neck where the carotid artery branches into the internal and external carotid arteries. The massage stimulates baroreceptors in the carotid sinus, which can help regulate heart rate and blood pressure.
