My sister says he is in atrial fibrillation with elevated heart and liver levels, elevated bilirubin - eyes are yellow. They suspect a virus may have set this off. It is killing me to be so far away, but sister says he's alert and doing okay in the hospital and that I should stay here and tend to my husband who is scheduled for surgery Thursday. She'll let me know if she needs me down there (it's a major trip to drive -- 10 hours). Rather stressed at the moment.
