[|Human|] My wife is 20 weeks pregnant and has an abnormally high heart rate. She did a 24 hour test and her average heart rate is 115. Her blood pressure is normal. The echogram showed no problems. She has to do a thyroid function test next week. Is this anything to be concerned about?
[|AI|]  Hello, and I hope I can help you today. Many women experience a fast heartbeat while they are pregnant, and as long as the doctors' evaluation of her heart as well is for other medical problems the can cause rapid heartbeat, such as thyroid disease, are negative than the symptom is likely just due to pregnancy. A pregnant women blood volume increases to one half times greater capacity during pregnancy to provide the placenta with oxygen as well is prepare her body for childbirth, so during the adjustment period, her body may just be under some additional stress. Furthermore, if your wife has gained a lot of weight since the beginning of the pregnancy, even ordinary activities can make her heart race compared to when she is not pregnant. So in summary, as long as your wife is under proper medical care and receiving an evaluation, there really is no reason to worry. Furthermore, your wives rapid heartbeat does not have any negative effect on the fetus, so there is no need to worry about the baby in the situation. I hope that I was adequately able to answer your question today, and that my advice was helpful. Best wishes,
