Metoprolol
"Supraventricular Tachy with Arrhythmia runs in our family. When I was 6 years old a Doctor yelled heart attack, I thought he was having one and he thought I was having one. The nurse calmed him down. I obviously compensated from having it so long. So, that was how it was till I was about 28. Then my heart rate was 180 a minute all the time. I could not compensate. I was told to go on heart medicines. I am allergic to a lot of things and do not respond well to things. So after about dying from trying beta blockers I was put on Corgard which worked perfect. Now my insurance will not cover it. I am 56 and just put on Metoprolol and scared. I hope it works well and I have no problems."
