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.
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.
There are many signs of fetal distress such as cramping, umbilical cord issues, gaining weight, fetal movements, high blood pressure, and fetal heart rate.
rate at birth
Don't know for sure. We just had ours measured at 8 weeks 0 days, and it was 168. Web using Google seems to imply that fetal heart rate peaks at 9 weeks of development, and 179 isn't way too high. But you should do the search yourself. I used this search: heart rate week fetal OR fetus One source says: "Beginning at a rate near the mother's, at approximately 80-85 B/M at the start of the 5th week, the heart rate accelerates to a mean of 175 B/M (+/-20 = 2SD) at 9.2 LMP weeks. It then abruptly begins to decelerate. This increase is approximately 10 beats every 3 days until the early 9th week." Note that LMP = last missed period; meaning, the conventional measurement of gestational age. Another source says "Normal heart rate at 6 weeks is 90-113 bpm and at 9 weeks is 144-170 bpm." So...it's hard to say. Sounds like it's not way to high to me. BUT ASK YOUR DOCTOR.
Fetal Heart Rate
Starting at week 5 the fetal heart will accelerate at a rate of 3.3 beats per day for the next month. The fetal heart begins to beat at approximately the same rate as the mothers, which is 80 to 85 bpm. Below illustrates the approximate fetal heart rate for weeks 5 to 9, assuming a starting rate of 80 Week 5 starts at 80 and ends at 103 bpm Week 6 starts at 103 and ends at 126 bpm Week 7 starts at 126 and ends at 149 bpm Week 8 starts at 149 and ends at 172 bpm At week 9 the fetal heartbeat tends to beat within a range of 155 to 195 bpm. The fetal heart rate will begin to decrease and generally will fall within the range of 120 to 160 bpm by week 12

Yes that is a very strong heartbeat, heart rates should be between approximately 110 and 160 beats per minute, although they can reach as high as 170 or 180 and as low as 100 and still be considered normal. The average will vary from baby to baby and will rise and fall throughout pregnancy.
Doctors monitor the heart rate of the growing fetus to make sure there are no abnormalities and that the child is healthy.
Fetal monitoring is a process in which the baby's heart rate is monitored for indicators of stress during labor and birth.
