I to have had the same problem!! I am currently 22 weeks pregnant and for about a month and 1/2 Ive had spells where i would get flush and feel dizzy and as though my heart was coming out of my chest. It has gotten up to 145. My blood pressure is also very low around 90/62. I have had an ekg and go next week to get a heart monitor to wear for 24 hours to see if it may be my heart acting up??? my doctors seem to have no clue what is going on and i feel like a complete fool bc everytime i go to the dr ive beem sitting down in the waiting room for an hour and so i feel fine and everything is ok for the time being. It is mainly while i am standing. One of the dr's said it could be pregnancy induced since your blood doesnt circulate as good in your legs when you are pregnant,and while your are standing your blood pressure lowers bc of this- which in return makes your heart rate go up to try and compensate??? i dont know if this will help bc i dont even understand it- but maybe it will help a little?

I am in my 25th week of my third pregnancy and I have endured this problem with all three pregnancies. good news is my babies were both healthy and fine, however I am not. I have discovered my Heart rate to increase rapidly from walking up the stairs, but mostly a reaction to carbohydrates and sugars. I don't know if this is what happens to you guys or not, but at about 16 weeks my pregnancy becomes so difficult to understand. My heart rate will usually jump up to 90 to 148 was my highest ever and can last up to 45 minutes of unbearable feelings, of dizziness, I feel like I can't breath. Once each pregnancy i have actually lost my vision,like a blacking out,but somehow I am still conscious. That has always happened when I am in the sitting position. I am writing because I have had an ekg, they found nothing wrong. HEllo I am not making this up and it can't be normal. Lately I 've been feeling like it starts when the blood really increases in my body. I just want help. I love babies, but for five months of my pregnacy, I start to go crazy. I have found that if I start my day off with protein, it helps. If I eat small amounts of high protein food through out the day it helps. But you can't put a pregnant women on a no carb diet. Even an apple will set this heart rate off. I want help, my doctor says well your babies have been, fine but no one has ever monitored what is going on with baby will i'm experiencing 125bpm 4 times a day. please if anyone has any answers I need help.

please tell me my granddaughter rapid heartbeat is normal.
her doctor said it was o.k when she was checked at 3 months but it still beats rapid sometimes and she now 5 months

I am 10 weeks pregnant and for the last 3 weeks I have been experiencing episodes of rapid heart beat. In the beginning it was not that bad and would only last a few seconds. Now It last for about 40 minutes and than I am fine for a few hours. Is this normal to happen so early in pregnancy. This is my second pregnancy and I did not experience this with the first one.

I have been having similar issues where my HR will jump at random times during the day to 120 and then I feel extremely tired. After I sleep, my heart rate returns to normal. I am 23 weeks. I had some issues with chest pain and my heart racing before i got pregnant. I didn't know it, but I was experiencing panic attacks.... they would come at really random times. They put me on Prozac and it helped tremendously as in I was back to normal and even felt like I had more energy. Well when I got pregnant I weened myself off of them & then this started with the jumping heart rate. My doc just put me back on my prozac... she said it is very possible that my anxiety issues are returning (especially with all the anxiety associated with pregnancy). I have only been back on my meds for 2 days. I will try to keep you guys posted, but this may be something that you might want to ask your doc about.... and see if it is anxiety related. Panic attacks can literally feel like a heart attack or stroke.
