Racing heart?

So I'm finding myself feeling my heart race here and there. Mostly at night when I'm trying to go to sleep. My heart will race and I start to breath heavy. I notice I get this to when I get Braxton hicks or if the baby moves but someone's it's none of these things and it just happens. Is this normal? I'm 33 weeks.

Re: Racing heart?

its normal. i had heart palpitations around 25 weeks. I never had this before so I went to my ob and a cardiologist. I had ekg's and an echo cardiogram. everything was perfectly fine with my heart. both docs said this is normal because your heart is producing blood for two and is working a lot harder than it normally does
