Usually this is not possible condition for a fetus
The baby's heart begins to beat at about five weeks after your last menstrual period, or three weeks after conception. It can be visualized with an ultrasound, but not heard with a Doppler until later in the pregnancy.
A normal heartbeat of a fetus at 6-7 weeks would be 90-110 beats per minute.
At 25 weeks!
100
I am now 9 weeks. When I was 8 weeks my baby's BPM was at 164.
Doctors monitor the heart rate of the growing fetus to make sure there are no abnormalities and that the child is healthy.
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.
Boy or girl, the heart rate of the fetus is 144 per minute. It is miraculously constant. It is a great pleasure to listen to the fetal heart beats. You can put the stethoscope in the ears of the mother and then see her expressions. See the expressions of the father, when he listen the heart beats of the fetus.
fetus is very small, the heart is very small so to pump enough oxygenated blood thru the developing fetus it must pump much faster than than an adult heart
As early as 24 weeks, although this is not a 100% survival rate.
Nope
It all depends on how old the fetus is. At the beginning, it is about 80-85, but steadily rises to 155-195 as time goes on. For more information, check this website out. http://www.i-am-pregnant.com/encyclopedia/F/Fetal-Heart-Rate/
