oculocardiac reflex

a slowing of the rhythm of the heart following compression of the eyes. A slowing of from 5 to 13 beats per minute is normal; one of from 13 to 50 or more is exaggerated; one of from 1 to 5 is diminished. If ocular compression produces acceleration of the heart, the reflex is called inverted. Called also Aschner r. or phenomenon.
