Fetal heart rate of 150 beats per minute or above does not indicate a boy or a girl. Fetal heart rate refers to the number of times the fetus beats per minute. Under normal circumstances, the reference range of fetal heart rate is 110-160 beats per minute, and the fetal heart rate of 150 beats per minute can occur in both boys and girls. Therefore, a fetal heart rate of 150 beats per minute is not indicative of a baby boy or a baby girl. Abnormally lowered or abnormally increased fetal heart rate suggests that there is intrauterine hypoxia in the fetus, which can lead to fetal death, neonatal ischemia, hypoxic encephalopathy and other adverse consequences if the duration of intrauterine hypoxia is too long. If the fetal heart rate is abnormal, you should seek medical treatment as soon as possible, and terminate the pregnancy if necessary, so as to avoid delaying the condition, which may lead to adverse pregnancy outcomes.
