I get a racing heartbeat every once in awhile. When I was pg with DS1, I had it quite frequently (sometimes multiple times a day). I even went to see a cardiologist about it, and they put a monitor on me, but it was just a random rapid hb. They said that pregnancy can cause it. Well, I didn't have it with any other pregnancies, but it's coming back now with a vengeance. Yesterday, it was so bad that I had to lie down and put a cold washcloth on my face, and that barely seemed to help. Anyone else experience this (now or on the past)?
