The hypertensive carotid sinus can be divided into cardioinhibitory (chronotropic) and vasodepressor components; the former can be evaluated by carotid sinus massage performed in the supine position. We present the case of a patient in whom the abnormal cardioinhibitory response could only be demonstrated while in the sitting position.
