update

My dad has been switched off the IV antibiotics to oral antibiotics, his blood pressure has returned to normal, and he has no more fever.  All those suggested that he was going to be discharged from the hospital today.  But last night, his heart decided to start acting up and he's been having on and off bouts of atrial fibrillation.  At least, that's what we're calling it right now.  That's based on how it feels to my dad since he's pretty familiar with this condition having been diagnosed with it back in 2006.  Given the current circumstances, they're going to play it safe and keep him there.  They've requested a cardiology consult and are in the process of getting all his cardiovascular medical records from the Texas Heart Institute down the street.  So it'll be at least one more night in the hospital.  That'll make 4 nights/5 days.
