This is also known as Stokes-Adams or Adams-Stokes syndrome, it probably should be termed Morgagni-Adams-Stokes syndrome.
In 1827, Robert Adams described a syndrome in which cerebral symptoms and decreased pulse occurred in association with heart block. A previous inkling of this association was described by Morgagni (1682-1771) (foramen, hernia) the famous Italian anatomist / father of pathology.
William Stokes (1804-1878) subsequently confirmed the pathology, as a syndrome characterized by attacks of unconsciousness, slow pulse, and occasionally convulsive seizures or uncontrollable giddiness.
