Is it dangerous for me to get my heart rate over 140 beats per minute during pregnancy?

Pregnancy findings: The heart rate goes up through pregnancy, at rest and during exercise. Some arrhythmias can flare up during pregnancy as well (including those that are not dangerous).

The : The pulse typically does go up during pregnancy, the the blood pressure usually goes down. I am glad that you had an extensive evaluation including an echocardiogram. However obtaining a second opinion is always a good idea and may put your mind at rest as well. Be sure you are staying well hydrated. Be sure that your thyroid testing was normal. Eating 4-5 small high protein meals a day is advisable during pregnancy. ...Read more

What is a growth scan for in pregnancy? Will they check my baby's heart? I wanna know the heart rate! What will they measure in this scan? I'm 34weeks

Growth scan: A growth scan is an ultrasound to see that the baby is growing appropriately. They will take various measurements from which they will compare to those from a previous ultrasound to be sure they have grown enough and not too much. The baby's heart beat should be checked at each visit and you can ask what it is even without a scan. It should vary just as yours does. Hope this helps. Best wishes. ...Read more
