I was put on a beta blocker, which helped a lot, and posed a very low risk to the baby (low birth weight, and low blood glucose
levels are a possibility, but my daughter was fine). If your EKG and your heart structure and function are normal then you don't need to worry! No need to think of terminating the pregnancy. The worst part of it all is the anxiety it can cause you when you have symptoms, or even just worrying about it.
