The anxiety doesn't help. I remember pushing my baby in a stroller around the fire station in case I passed out! Your hormones are adjusting, perhaps. I hope you can feel it is possible things will smooth out. In my experience doctors don't take this very seriously because PVC's aren't seen as dangerous. But they do take a toll on you. If you try beta blockers hoping they help, or diltiazem (calcium channel blocker). As I said, tai chi helped me a lot. Good luck!
