Make a visit.
If there's ever a time to have a good, sit down, heart-to-heart with your cardiologist, this is it.
with svt depends on a lot of things - how old your are, if you have other heart disease, if your svt is controlled by meds or not, how often you get it. When you see your cards doc, ask specific questions: ex "how high should I let my heart rate
get and for how long?" good luck!
