I had this exact situation about 6 weeks ago. Heart rate crazy high, BP wasn’t an issue though but all other signs of preeclampsia. I’m now on labetalol 200mg twice a day and feel wonderful. And they have me doing growth scans to make sure there’s no issues there and she’s growing perfectly healthy!
@Tara I had an episode Sunday where I was super weak , couldn’t move. Painful shoulders and upper back. High heart rate. Out of breath. He is referring me to a cardiologist now. But to continue meds. I will say the meds do make me feel a little better. I wonder if I need a higher dose

I had pots pre-pregnancy but during pregnancy I did learn that pregnancy can cause an onset of POTs https://www.awarenessforpotsies.org/pregnancy-with-pots#:~:text=Unfortunately%2C%20yes%2C%20some%20find%20that,navigating%20an%20illness%20like%20POTS.
