If the heart beats too fast, contractions are shallow and not enough blood is pumped with each heartbeat. As a result, the fetus can go into heart failure. The most common form of this condition is called supraventricular tachycardia (SVT), in which the heart rate can be faster than 200 beats per minute.
When should I be concerned about my baby’s heart rate?

Is fetal heart rate of 170 too high?
A rapid fetal heart rate is termed a fetal tachycardia and is usually defined as: FHR >160-180 bpm. FHR around 170 bpm may be classified as borderline fetal tachycardia.
What causes high fetal heart rate?
There are a number of maternal conditions that increase the likelihood of tachycardia in the fetus. Hyperthyroidism secondary to thyroid stimulating antibodies, fever associated with systemic infections and substance abuse may result in an increase in the fetal heart rate above the normal range.
