Your healthcare provider may do fetal heart monitoring during late pregnancy and labor. The average fetal heart rate is between 110 and 160 beats per minute. It can vary by 5 to 25 beats per minute. The fetal heart rate may change as your baby responds to conditions in your uterus.

Aim. There is no consensus about the normal fetal heart rate. Current international guidelines recommend for the normal fetal heart rate (FHR) baseline different ranges of 110 to 150 beats per minute (bpm) or 110 to 160 bpm.

Normal Values Newborns (0 - 3 months old): 100 - 150 beats per minute. Infants (3 - 6 months old): 90 - 120 beats per minute. Infants (6 - 12 months old): 80 - 120 beats per minute. Children 1 - 10 years: 70 - 130 beats per minute.

Newborns 0 to 1 month old: 70 to 190 beats per minute. Infants 1 to 11 months old: 80 to 160 beats per minute. Children 1 to 2 years old: 80 to 130 beats per minute. Children 3 to 4 years old: 80 to 120 beats per minute.

For resting heart rate: Newborns 0 to 1 month old: 70 to 190 beats per minute. Infants 1 to 11 months old: 80 to 160 beats per minute. Children 1 to 2 years old: 80 to 130 beats per minute.

After the rate reaches an average of about 175 beats per minute, studies show, the acceleration reverses; by the middle of pregnancy, the rate averages 120 to 160 beats per minute.

A normal heart rate is generally stated to be between 60-100 beats per minute at rest (sitting, relaxing, etc.). However, recent studies (here and here) have suggested that an ideal resting heart rate is between 50-70 beats per minute.

The mean basal heart rate of 148 bpm at a median gestation of 161 days (23 weeks) is within the 110-160 bpm normal range for viable fetusses (11). The finding of more accelerations than decelerations is in contrast to previous reports based on ultrasound recordings at this gestational age.

Gestational Age Week 7 (Fetal Age: 5 weeks) Generally, from 6 ½ -7 weeks is the time when a heartbeat can be detected and viability can be assessed. A normal heartbeat at 6-7 weeks would be 90-110 beats per minute. The presence of an embryonic heartbeat is an assuring sign of the health of the pregnancy.

Normal Results For resting heart rate: Newborns 0 to 1 month old: 70 to 190 beats per minute. Infants 1 to 11 months old: 80 to 160 beats per minute. Children 1 to 2 years old: 80 to 130 beats per minute.

If you exercised regularly before pregnancy, there's no need to focus on your heart rate for exercise during pregnancy. Years ago, some experts recommended a heart rate of no more than 140 beats a minute for exercise during pregnancy. Today, however, heart rate limits aren't typically imposed during pregnancy.

The average heart rate for baby boys in the first trimester was 154.9 bpm (plus or minus 22.8 bpm) and for baby girls it was 151.7 bpm (plus or minus 22.7 bpm). In other words, this myth is busted. There was not a significant difference between male and female heart rates during early pregnancy.

The normal range for the rate of the baby's heartbeat is between 110 and 160 beats a minute, although this can be higher or lower without meaning that the baby is in difficulty. The variation in the baby's heart rate may be caused by the womb contracting, which affects the blood flow to the placenta (afterbirth).

Heart rate. One of the most universal myths about gender revolves around your baby's heart rate. If the beats per minute are under 140, the baby is supposed to be a boy. Higher than 140, it's a girl.

A normal resting heart rate for adults ranges from 60 to 100 beats per minute. Generally, a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness.

A fetus's heart rate will usually range between 110 to 160 beats per minute (bpm), but it can vary throughout pregnancy. The baby's heart rate could increase all the way up to 170 bpm.

Evolution through gestation The FHR is then usually around 100 to 120 beats per minute (bpm). FHR then increases progressively over the subsequent 2-3 weeks becoming 7: ~110 bpm (mean) by 5-6 weeks. ~170 bpm by 9-10 weeks.
