I was recently diagnosed with A Fib. Spent 3 days in the hospital. I am 68, healthy, great BP 110/70, cholesterol really good, pulse normally about 60 -65. Had a lung infection, then went to poor breathing. End results was A Fib One of the meds along with lasik and a blood thinner was Metoprolol. It keeps bumping my blood pressure down into the low 90 s and and 80 s. Why are they giving me this when my blood pressure is good. It doesn t seem to help my heart rate. Thanks Diana YYYY@YYYY
