My new doc. wanted to try another BP med. for my High BP. My pulse with Beta got too low (45-52), but now without it is back where it was before Beta, at 103-109. My bloodpressure is stable with this new med. though. Does anyone else have Tachycardia, and do you know why you have it?? My doc. want to give a definitive diagnose of FM, he have drawn gallons (LOL!) of blood and took a chest x-ray. I haven't got the results yet. My pulse races crazy as soon as I excert myself the slightest.
