A pulsation occasionally noticed in the jugular veins. It is owing to some of the blood of the right ventricle reflowing into the right auricle, and communicating an impulse to the venous blood arriving in the auricle through the descending cava. It is often a sign of impediment to the flow of blood along the pulmonary artery.
