I am pregnant 28 weeks fetal heart rate 167 normal?

Normal fetal heart rate during pregnancy is 120~160 beats/minute, fetal heart rate tachycardia is found in maternal fever, maternal anemia, hyperthyroidism, fetal heart defects and other factors, the current fetal heart rate is 167 beats/minute, if no obvious abnormality is found, fetal heart rate faster is irrelevant, belongs to the normal fluctuation range.
