Adams-Stokes Disease (also known as Stokes-Adams disease) is a temporary condition that leads to fainting, or syncope. It is caused when a slow-firing sinoatrial (SA) node interrupts the electrical signals traveling to the ventricles of the heart. This results in an inadequate flow of blood to the brain because the heart is beating too slowly (an arrhythmia known as bradycardia). If the electrical signals from the atria fail to travel beyond the AV node to the ventricles, it causes heart block.
