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.

Babies’ hearts beat much faster than their parents’, both to fuel their growth and make up for greater heat loss to the environment. So little hearts maintain a higher metabolic rate, pound for pound, than big hearts.

At about 5 weeks gestation, your baby's heart begins to beat. At this point, a normal fetal heart rate is about the same heart rate as the mother's-about 80-85 beats per minute (BPM). From this point, it will increase by about 3 beats per minute per day during that first month.

Typically the heart beat can not be heard with even a doppler until the 9-10th week of pregnancy at the very earliest (sometimes not until the 12-14th weeks of pregnancy). A baby's heart beat is very rapid, much faster than an adult. In fact it starts out near 180 beats per minute (BPM) and around 12 weeks gestation settles into the normal range of 120-160 BPM for the remainder of the pregnancy. Even though you can not hear the fetal heartbeat until week 9 or 10, ultrasound is able to see a beating heart much sooner.

I had my midwife appt on monday, and when i looked at my notes LO's heartbeat was 156, the past few appointments it shows around 130-135, so mines has increased too! He wasnt moving much at the time either. Hopefully someone will have an answer, my midwife was happy with his heart rate though.

A fetal echocardiogram is a detailed ultrasound performed of the baby's heart before the baby is born. A small camera called a transducer is placed on the pregnant mother's abdomen and sends out ultrasonic sound waves.

Updated:Jan 8,2015. Congenital heart disease is a problem that occurs with the baby's heart while the baby is still developing. It's seen in approximately 1% of babies born in the United States and is the most common form of birth defect. The baby's heart begins to form immediately after conception and is complete by eight week's gestation. The heart begins as a tube shaped structure that twists and divides to form the heart and heart valves.

Newborns have resting heart rates around 100 to 150 beats per minute, way higher than that of adults. In fact, a newborn’s resting heart rate is in the ballpark of the target heart rate for an adult doing a heavy workout.

Picture new parents cooing at their baby on the couch. The baby’s quiet and calm, and everyone’s at rest. So their heart rates are low, maybe 60 or 70 beats a minute for the adults.
