@kdoll I would be interested to know which supplements you are taking. I have been prescribed Metoprolol (by my PCP although we did not talk about it) after the Zio monitor I wore (great little device!) for 14 days indicated SVT. I did fill the prescription but have not begun taking it because, for one thing, the dizzy spells have disappeared after months, and those were my primary symptoms….and yet taking beta or calcium blockers indicate dizziness as a main side effect!

So I am in wait and see mode.

Have been waiting a long time to get in to see a cardiologist so I can discuss and go on April 1st.

I also am one of those who knows my body best and I do not always concur with what the doctor ordered. Not all doctors appreciate skepticism but I think it is healthy. I have never taken drugs except for surgery for a broken wrist and that took about six months to leave my system, but those are heavy duty anesthesia drugs.
Plus I am 80, pretty healthy, but the SVT is a concern and I will keep exploring what if anything is necessary. Thank you for sharing your experience. It is really interesting to browse these forums because it is obvious that “one size fits all” is not always an answer to our symptoms.
