Fetal Tachycardia Symptoms – Causes and Manifestation

No parent ever wants to think about the fetal tachycardia symptoms.

It is good to know that the normal heart rate of the baby during the 30th week of pregnancy is of 120-160 bpm and at term the heart rate is supposed to be of 110-150 bpm.

Fetal Tachycardia Symptoms


If the heart rate of the baby is of 170 bpm, it is said to be slightly abnormal but if it exceeds 180 bpm, the baby is said to be tachycardic. Usually the doctors recognize the problems during the prenatal visits. In order to exclude the structural defects the doctors use fetal echocardiography.

What to look for

It is important to remember that fetal tachycardia isn’t associated with increased heart rate during activity or excretion. Nonetheless the parents should be looking for some other signs and symptoms, such as excessive fatigue or sleepiness of the baby.

In the same time when thinking about fetal tachycardia symptoms you should expect to see fuzziness and there could be changes when the baby is doing some kind of activity. The truth is that there aren’t too many symptoms that would indicate the problem.

Causes of the signs of the fetal tachycardia

The truth is that the condition is usually benign. However if the condition lasts for longer time you should be looking for different kinds of factors. One of the most common causes of the problem is maternal fever that leads to maternal ketosis.

The parents thinking about the fetal tachycardia symptoms should know that the anxiety and the dehydration of the mother can also be a contributing factor. The sad truth is that the majority of the premature babies are also affected by the problem.

Some other warning signs of the fetal tachycardia are caused by thyrotoxicosis or anemia of the mother. Serious causes of the symptoms include congenital heart defect (also known as chiroamnionitis) and fetal arrhythmia. It is interesting to know that the excessive fetal movements can cause the problem too. Usually mothers are happy about the fetal movements, but as you can see, they can cause some problems as well.

Although it’s sad to think about the fetal tachycardia symptoms, the good news is that the doctors always find the problem and there are some treatment options that work out for the of the babies so that they will have a normal life.
