I have mild MVP and had all the EKG's, Echo's, Holter and Event Monitor's galore. Always been told my heart is fine. When the MVP first started in my early 20's it was just Sinus Tachycardia. The older I have gotten the more PVC's have come ( I am 35). First it was ocassionally, now they are coming in a series and when they come one right after the other they feel more like flutters like it cant catch up and I feel nasueaous (not like the normal thud), but I have not felt faint at this point and it has shown my heartbeat to be irregular on blood pressure monitor but blood pressure and heart rate were normal. Once again told they were benign and my heart is fine. Put me on Atenolol 25 mg a day...told me I can increase if I need to, but it seems to me that this beta blocker makes me sleepy and depressed lowers my blood pressure and now I wonder if the slowing of the heart rate is not making my skips worse. Should I increase my atenolol, stop my atenolol or should I try Magnesium. I have heard alot of people say that Magnesium has helped them. If I do stop taking the atenolol I know you are not supposed to stop all together how should I wean myself off of it, again I take 25 mg a day...sometimes I even skip a day.
