Your baby's heart rate is less than 110 beats per minute. Your baby's heart rate is more than 160 beats per minute. During a nonstress test, your baby's heart rate does not increase by 15 beats per minute or drops far below its baseline rate (deceleration) after he or she moves.
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.
