After doing some more reading this seems like
another interesting possibility:

"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."
Would explain why he is wearing it while on his ranch:

So it wasn't a pretzel that caused him to faint back then?
