Fetal heart rate by week

    • What is the average fetal heartbeat at 20 weeks?

      The normal FHR keeps changing during gestation and can get up to 170 beats per minute at 10 weeks. However, the heartbeat usually becomes slower from 10 weeks and is usually around 130 bpm at term. Fetal heart rate at 20 weeks is somewhere around 140. Here is a chart for more details about the normal heart rate at different stages in pregnancy.

    • What is considered a normal fetal heart rate?

      Fetal heart rate is a medical term that refers to the heart rate of the fetus. Its normal value is generally 110 to 160 beats per minute. The fetal heart rate is regulated by the sympathetic and parasympathetic nerves.

    • What is the normal heart rate of a full six week old fetus?

      A normal fetal heart rate (FHR) usually ranges from 120 to 160 beats per minute (bpm) in the in utero period. It is measurable sonographically from around 6 weeks and the normal range varies during gestation, increasing to around 170 bpm at 10 weeks and decreasing from then to around 130 bpm at term.

    • What can cause increased fetal heart rate?

      What causes high fetal heart rate? There are a number of maternal conditions that increase the likelihood of tachycardia in the fetus. Hyperthyroidism secondary to thyroid stimulating antibodies, fever associated with systemic infections and substance abuse may result in an increase in the fetal heart rate above the normal range.

      The acme is > 15 bpm above baseline, lasting > 15 sec. & < 2 min. from onset to return to baseline. The increase is calculated from the most recently determined portion of the baseline. In fetuses < 32weeks, acme >10bpm above the baseline and a duration of >10 sec. Prolonged acceleration is > 2 min. and < 10 min.

      The normal baseline fetal heart rate is defined as 110 – 160 bpm. Fetal bradycardia is a baseline rate of 160 bpm. Many fetal baseline bradycardias have no identifiable cause but may occur as a result of: • Cord compression and acute fetal hypoxia • Post-maturity(>40weeksgestation ...
