The nurse Jul 15, 2002 · Background— Although the prenatal diagnosis of most fetal structural heart defects and dysrhythmias has been described, there is a paucity of information about cardiomyopathies (CMs) in prenatal life. Elderly people, for example, are more prone to bradycardia. Early decelerations in the FHR are associated with head compression as the fetus descends into the maternal pelvic outlet; they are not generally a concern during normal labor. This is called a conducted PAC. They occur in 1 to 2 percent of pregnancies. They can reach the fetus and affect its heart rate. It is also common for the fetus to have an irregular rhythm.

The three-tier fetal heart rate tracing system is one of the valuable means in classifying the severity of the fetal oxygenation status. D. Fetal arrhythmias can lead to changes from this regular pattern. d. Confusion or memory problems. The baseline rate should be within the normal range. On the contrary, in a gradually evolving hypoxic stress, there is sufficient time to mount a catecholamine-mediated increase in the fetal heart rate to increase the cardiac output and redistribute oxygenated blood to maintain an Fetal heart rate, baseline variability, and decelerations are used to assess characteristic and pattern changes in the fetal heart rate.
