rate at birth

By the beginning of the 9th week of pregnancy, the normal fetal heart rate is an average of 175 BPM. At this point it begins a rapid deceleration to the normal fetal heart rate for the middle of the pregnancy of about 120-180 BPM. There is also a slowing of the normal fetal heart rate in the last ten weeks of pregnancy, though the normal fetal heart rate is still about twice the normal adult's resting heart rate.

No, that is within normal range.

An irregular fetal heart rate at 24 weeks could mean a variety of things. It could mean that the baby's heart rate is just slower, then faster. It could also mean there is a problem with the heart. The doctor should advise you if there are any problems.
