The fetal heart rate baseline is a measure of the average heart rate of the fetus during pregnancy. The normal fetal heart rate baseline ranges between 110 to 160 beats per minute (BPM). Therefore， a fetal heart rate baseline of 143 BPM falls within the normal range， indicating that the baby is healthy and developing well.
It is important to note that fetal heart rate can fluctuate throughout pregnancy， and this is generally considered normal. Factors such as fetal movements and maternal activity can affect the fetal heart rate. Fetal heart rate variability is also considered normal and is an indicator of a healthy fetal nervous system.
However， if there are persistent abnormalities in the fetal heart rate， it can be an indication of fetal distress. Fetal distress can be caused by a variety of factors， including maternal health， umbilical cord problems， and placental issues. In such cases， immediate action needs to be taken to ensure the well-being of the baby.
In summary， a fetal heart rate baseline of 143 BPM is considered normal， but it is important to monitor the fetal heart rate throughout pregnancy to ensure that it remains within the normal range. If there are any concerns or abnormalities， it is important to consult a healthcare provider immediately.
