Adams-Stokes disease is marked by a sudden collapse into unconsciousness due to a disorder of heart rhythm in which there is a slow or absent pulse resulting in fainting with or without convulsions. In this condition, the normal electrical flow passing from the upper chambers of the heart to the lower chambers is interrupted. This results in a condition called a “heart block.” When a heart block occurs, the AV node takes over for the sinus node in setting the heart rate which then usually slows considerably. This can cause inadequate blood flow to the brain and result in fainting. This condition goes by a baffling number of names including the Adams-Stokes disease, Morgagni disease, Morgagni syndrome, Morgagni-Adams-Stokes, Spens syndrome, and Stokes-Adams disease or Stokes-Adams syndrome.
