Fetal Arrhythmia at 34 Weeks Pregnancy: Should I Be Concerned?

I am 34-weeks-pregnant and my obstetrician says that my baby has fetal arrhythmia. He made an appointment for me to see a perinatologist next week. Can you tell me what this means?


An arrhythmia is an abnormal heart rhythm. Usually it is not associated with any problem of heart formation, although in rare cases, it is possible. If it has not been heard before, it is almost always not dangerous to the baby. However, to be on the safe side, it should be evaluated.

Most of the time, it stops on its own in a few weeks. Occasionally, it persists and needs to be evaluated by the pediatricians after birth. We don't know all the causes, but one of the more popular theories is a viral infection that causes an irregular beat for a few weeks. After that, the baby gets better.
