I found out on new years night that I was pregnant with baby number 2. Lately I’ve been having severe anxiety and panic attacks. And horrible rapid heart rate. I went to the er and everything came back normal my ekgs came back good, blood work was good and thyroid was good. My resting heart rate will be 60’s - 90’s but as soon as I stand up my heart will just pound and go to 120-140 even has hit 160. Is this normal? Has anyone had this ? I’ve never had this with my first pregnancy.
