Women 9 weeks pregnant, fetal heart rate 178 beats per minute, generally considered fast, may be physiological or pathological factors. 1. Physiological factors: during pregnancy, the normal fetal heart rate is generally between 120 and 160 beats per minute, so the fetal heart rate of 178 beats per minute is on the fast side. If the fetal heart rate increases for a short period of time, it is generally considered to be caused by physiological factors, and it is recommended to continue to receive monitoring and does not require special treatment. 2. Pathological factors: if the fetal heart rate is maintained at 178 beats per minute for a long time, or constantly accelerated, this situation is abnormal, may be induced by intrauterine hypoxia, it is necessary to receive early examination and treatment to avoid affecting the health. In addition, during pregnancy, women are advised to closely observe the changes in fetal heart rate, and actively receive treatment when necessary.
