Fetal hearth rate tells you how fast a fetus would warm up if you placed in in front of a fireplace.
Yes it does need to be 20 minutes long, at least. It takes 20minutes to accurately asess a fetal heart rate baseline. We are looking for two accelerations of 15beats above baseline during that 20minutes.
This is a myth, there is no link between fetal heart rate and the sex. Here is one particular study that proves this:http://www.obgyn.net/medical.asp?page=/english/pubs/features/dubose/ehr-ageDC
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.
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
In the fetal hear the fossa ovalis was known as the foramen ovale, which allows blood to pass from the right to the left atrium, thus bypassing the fetal lungs.

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.

There are many signs of fetal distress such as cramping, umbilical cord issues, gaining weight, fetal movements, high blood pressure, and fetal heart rate.
Fetal monitoring is a process in which the baby's heart rate is monitored for indicators of stress during labor and birth.

Fetal monitoring is used to check your baby's heart rate while pregnant. During contractions, fetal monitoring is used to see how the baby tolerates and responds to contractions.
because it is differenece is size, and heart rate.
Electronic fetal monitoring (EFM) is a method for examining the condition of a baby in the uterus by noting any unusual changes in its heart rate
