George W. Bush apparently is wearing a medical device for "persons at
risk of cardiac arrest." It is a LifeVest wearable defibrillator. He
started using it sometime after his January 2002 fainting spell, which
was attributed to choking. Based on photos showing him wearing the
device, one can conclude the fainting was due to atrial fibrillation
(AF), which his father also had. His father's AF was caused by Graves'
hyperthyroidism, which his mother also has. Bush likely has AF and less
likely Graves', based on his family history and symptoms. The AF may
have caused a stroke or TIA (mini-stroke), of which physicians watching
the debates detected symptoms. Observers have noted psychological
symptoms consistent with this and with Wernicke-Korsakoff disease.
