What does my fast heart rate during pregnancy mean?

What does my fast heart rate during pregnancy mean?

High output: During pregnancy, here is a significant increase in plasma volume, creating a dilutional effect on one's blood counts (anemia). This coupled with the large flow of blood from maternal circulation to the placenta causes a compensatory rise in heart rate to generate the necessary cardiac output and deliver enough oxygen to the tissues.

Pregnancy (Definition)

When your due date arrives, you will be more than ready to have your baby! Most women deliver the baby somewhere between 37 and 42 weeks. According to the American College of Obstetricians and Gynecologists, only 5% of babies arrive on the exact due date. Approximately 7% of babies are not delivered by 42 weeks, and when that happens, it is referred to ...Read more

What is the normal heart rate for a 4 month baby during pregnancy?

145 + or - 20 points: Fetal heart rate is generally in the mid 140's, but may be 20 points or so higher or lower and is still considered normal. Factors that could affect rate would be maternal fever, illness, or activity. Irregular fetal rhythm would be more concerning.

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

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

Not necessarily: Heart may increase during pregnancy. I will recommend to see your pcp or a cardiologist to make sure that you have physiological tachycardia and not cardiac arrythmias, which is a possibility during pregnancy.

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). A resting heart rate of 140 is fast but not usually dangerous. But you should have your doctor do an ekg and/or heart monitor to ensure you are not having a rhythm abnormality that needs treatment.

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.

Good : Good plan to repeat the testing. Another possible cause is anovulation, where you didn't ovulate this month and are having hormonal symptoms rather than pregnancy symptoms. If your next test is negative you may wish to utilize supplemental hormones to re-synchronize your endometrium (uterine lining).

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

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.

When will movement be consistent in pregnancy ? I'm 26weeks and still haven't felt any movement his heart rate is strong and he is healthy

Later: Movement is occurring now, it just cannot be perceived by you at this time. By 30 weeks gestation, most pregnant moms to be can determine consistent fetal movement.

Is it normal to have 109-126 heart rate in the 9th month of pregnancy?And blood pressure between:142/80-129/74?

Is it normal to have 109-126 heart rate in the 9th month of pregnancy?And blood pressure between:142/80-129/74?

Yes: It's normal to have an elevated heart rate in pregnancy, especially toward the end. Any blood pressure > 140 / 90 needs to be evaluated by physician, but i'm assuming that your doctor already knows your blood pressure? Make sure you're well hydrated (pee should be clear colored, not dark yellow), dehydration can sometimes lead to an elevated heart rate. If on propranolol, speak with physician.

Early on in the pregnancy, are there any indications of the sex of the baby from the heart rate? My partner and i are really excited to know the sex of our baby, and we don’t want to have to wait for the ultrasound. We’re going to an early appointment thi

Old : Old wives tales suggest that girl fetuses have heart rates above 140, while boy fetuses tend to have heart rates lower than 140. Unfortunately, as sexy as it sounds to believe that we might predict a baby’s sex by the heart rate, it’s simply not true. Repeated studies have proven that fetal heart rate does not correlate to fetal sex, but it does correlate to gestational age. As fetuses develop, their heart rates tend to drop. As a mother, i know how impatient i was to discover that i was having a little girl, but i can tell you that the thrill i felt when i found out my baby’s gender made it well worth the wait.

What is the normal heart rate of human fetus at 17 weeks of pregnancy?

What is the normal heart rate of human fetus at 17 weeks of pregnancy?

About 140 (+or- 30): The fetal heart rate can vary considerably depending on the mother's heart rate and health and on the fetal metabolic state, level of activity and probably several other factors. Normally in a very quiet, relaxed postprandial or sleep-like state, it would tend to be low (115 to 120) ; at other times it could possibly rise to 150-160 beats per minute or transiently perhaps to 170-180.

Early pregnancy ultrasound showed baby right on at 8 weeks 1 day but with a heart rate of 185bpm. I though 120-180 was normal. Should i be concerned?

Early pregnancy ultrasound showed baby right on at 8 weeks 1 day but with a heart rate of 185bpm. I though 120-180 was normal. Should i be concerned?

Normal FHT's: "normal" fetal heart rates are as you have described above in your question. 180 or 185 is a distinction without a difference.

Is an increase in resting heart rate normal in 1st trimester of pregnancy?

Is an increase in resting heart rate normal in 1st trimester of pregnancy?

Yes: A woman's cardiac output may increase by nearly 50% during the first trimester. A portion of this increase is attributable to an increase of resting heart rate. One might see an increase of 10 or 15 beats per minute.

If I took indoethacin in my last weeks of pregnancy, should the fetal heart rate be monitored on a daily basis?

If I took indoethacin in my last weeks of pregnancy, should the fetal heart rate be monitored on a daily basis?

Depends: Indomethacin taken frequently over a long period of time can cause a transient change in the fetal heart circulation (in doctor speak it closes the ductus arteriosus). Small doses for only a few days, which is usually the only thing we would do, is not particularly dangerous. Check with your doctor on why you are taking it and whether monitoring is needed.

What is the percentage of having a successful VBAC after 1 c-sec no complications with 1st pregnancy. C-sec due to non reassuring fetal heart rate?

Almost: the same as before. Since the first cs was for heart tones and not failure to progress, you should have a 80 +\- percent chance of having a successful vaginal delivery. Find an OB who has a low CS rate. Not total CS but For a woman's first CS. My primary rate is 14 percent. That means for a woman with no prior CS, she has an 86 percent chance of a vag delivery. Good luck.

Heart Rate (Definition)
