Stokes–Adams syndrome (alternative eponyms include Adams–Stokes syndrome, Gerbezius–Morgagni–Adams–Stokes syndrome and Gerbec–Morgagni–Adams–Stokes syndrome)[1] is a periodic fainting spell in which there is a periodic onset and offset of blockage of heart due to disorder of heart rhythm that may last for seconds, hours, days, or even weeks before the conduction returns. Named after two Irish physicians, Robert Adams (1791–1875)[2] and William Stokes (1804–1877),[3] the first description of the syndrome was published in 1717 by the Carniolan physician of Slovene descent Marko Gerbec, which was 44 years after its publication quoted by Giovanni Battista Morgagni.
