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.
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.
In which the blood flow through the left side of the heart is obstructed.
The pericardium is the sac-like membrane surrounding the heart in the fetal pig, as well as in humans.

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.
NST: The Nonstress test is part of the formal antenatal test for fetal well being. It is considered formally reactive (good sign) if the fetal heart rate has two accelerations in 20 minutes that are at least 15 beats above the baseline heart rate and last for at least 15 seconds.
what are fetal heart
In the fetal heart it was called ductus arteriosis.
An enlarged fetal heart is called fetal cardiomegaly. Fetal cardiomegaly is a symptom of a number of congenital heart defects including tricuspid artesia, Ebstein anomaly, or twin transfusion syndrome.

Fluid around the fetal heart are a sign of a congenital heart defect. When fluid is found around the fetal heart, it is known as hydrops.
Abdomen is not enlarging, no fetal heart tone, no fetal movements and etc.
The fetal pig has a four-chambered heart and not three-chambered. The chambers are divided between the upper and the lower chambers.
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.
