The elevated heart rate is required to support the baby's rapid growth.
Some DetailFetal development is dependent upon adequate exchange of gases and nutrients within the placenta. FHR (fetal heart rate) is generally about twice as high as the typical adult resting heart rate in order to support the high nutrient and gas exchange levels as well as the disposal of metabolic waste required for proper fetal development. Typical FHR in a fetus of 20 weeks averages about 155 beats per minute, with the normal range falling between 120 and 180. By term that rate has decreased, averaging 140 within a typical range of 120 to 160. By contrast, a healthy adult typically has a resting heart rate of about 80.
Unusually low FHR can cause fetal acidemia, fetal acidosis and other fetal acid-base physiological problems. These, in turn often result in impaired fetal metabolism and impaired development.
Throughout a person's life, typical heart rate can be seen to closely parallel rate of growth, steadily declining with the decline of growth in the mid-teens:
- Fetal - 20 weeks - 120-180
- Fetal - term - 120-160
- Infancy - 120-160
- 12-35 months - 80-110
- 3-5 years - 70-110
- 6-12 years - 65-110
- 13-18 years - 60-90
- 19-61 years - 60-100*

Young children have a faster pulse rate than adults because their hearts are smaller and need to pump more frequently to deliver the necessary oxygen and nutrients to their growing bodies. Additionally, their metabolism is higher as they are rapidly developing and growing, which also contributes to a faster heart rate.
