Your baby’s heart continues to develop during pregnancy. In such a case your doctor will reschedule another scan in one to two weeks.

The upper limit of normal heart rate in two gestational age ranges (before 6.3 weeks and 6.3-7.0 weeks) was computed as the average of two values: mean heart rate + 1.96 standard deviations and the rate above which 2.5% of embryos in our population were measured. What Regulates the Fetal Heart Rate? Study design: In fetuses with specified abnormal nonreassuring fetal heart rate patterns, oxygen was administered to the mother, and fetal oxygenation was monitored with fetal pulse oximetry. The goal was to evaluate if there was any correlation between maternal blood glucose and fetal heart rate. Oxytocin is commonly used for induction and augmentation of labour. Oxytocin does not have a direct influence on the fetal heart rate (FHR) or on the controlling cardiac centres in the brain, as is the case with some anaesthetic and antihypertensive drugs.
