If the fetal heartbeat is occasionally 169 beats/minute, this may be normal. However, if it is consistently above 169 beats/minute, this is not normal.
The normal fetal heart rate is 110~160 beats/min. If the fetal heart rate is greater than 160 beats/min in a quiet state, this situation is not normal, and it is considered to be a fetal heart rate that is too fast, and it is possible that the fetus is suffering from oxygen deprivation.
If the fetus is active when listening to the fetal heart rate, or if there are uterine contractions, the fetal heart rate may be slightly fast, mostly transient, and most of them will return to normal after removing the triggering factors.
If the fetal heart rate is 169 beats/minute on occasional auscultation, it can be left untreated for the time being, and ultrasound or fetal heart rate monitoring can be done for observation. If all aspects of the examination are normal, it means that it is normal. However, if the fetal heart rate has been found to be relatively fast, it is likely that the fetus is hypoxic, and it is necessary to follow the doctor’s instructions for oxygen therapy in a timely manner.
