Eight years ago I went to the ER for atrial fibrillation and a high heart rate (around 180bpm)... the onset was sudden but not the first time... after two days of intravenous dosing of beta blocker meds and TWO cardio versions, I was still in Afib. Then suddenly, like the 3-4 other times it happened at home, all went back to normal. I do not have and never had high blood pressure, just a slightly higher than average heart rate (75-85 bpm) and a sensitivity to MSG, artificial sweeteners and big doses of salt... all of which will cause my heart to beat funny even while taking toprol xl.
I was told never to stop taking the med for any reason... then my mom who's on it for a heart attack, was told to stop taking it for 48 hours prior to some testing they wanted to do on her. After 2 days of no toprol, her blood pressure was NORMAL... when any other time it has always been higher while taking toprol xl. I need to know if I'm making things worse or what. I don't like toprol... it's always affected me in ways I don't like... so if I don't need to be on it, I don't want it. Of course my doc says I have to be on it from now on... and other docs say it shouldn't be taken long term. Does ANYONE know the truth about beta blockers, metroprolol xl?
