Metoprolol
"After having a constant heart rate of 110/20 even when resting, occasional heart palpitations, anxiety, and high blood pressure,  I was put on Metoprolol success ER 25 mgs, that I half to 12.5mgs. It's been wonderful!  I am so much more relaxed, my heart rate stays around 75 to 80. Blood Pressure stays in a normal  range.
Love it!  I'm female, 47, 5 2` ( 135lbs )"
