As a reward for no more arrhythmia, my dad got to lose the cardiovascular monitor.  In exchange, he got his UTI back.  Well, we presume it's a UTI.  The urine culture came back negative but all his symptoms point to a UTI.  Regardless, he started running a fever again last night.  It's been a low grade fever, but a fever nonetheless which is never good in a SCT patient.  Without knowing which bug they're fighting, they are switching IV antibiotics through trial and error.  So far, it's worked.
