The heart rate of a fetus at 11 weeks is about 110 to 160 beats per minute, but this varies from person to person, and regular checkups are recommended starting at 12 weeks of gestation. Generally, the fetal heart rate is more accurate when checked at 12 weeks of gestation, but it can also be checked at 11 weeks of gestation, except that it may not be audible from the abdominal wall. Fetal heart rate of 110 to 160 beats per minute is only an approximate range. Some fetuses may also have a slow or fast heart rate, so it is recommended to observe and record the fetal heart rate regularly to determine the range of its variation. If the fetal heart rate is >160 beats/min or <110 beats/min in late pregnancy, it is possible that the fetus is suffering from intrauterine hypoxia, and it is recommended to go to the hospital for examination in time.
