Why is a baby’s heart rate fast in the womb?
A very fast heart rate may be caused by abnormal firing of the nerves that are responsible for the heartbeat. 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.
