Abstract:
In a prospective study of 3,083 patients having antenatal cardiotocography it was shown that ominous fetal heart rate traces were most likely to occur when the test was applied in specific 'at risk' situations rather than as a routine screening test, and when the need for monitoring was perceived relatively early in the pregnancy. The majority of ominous traces were not preceded by a normal trace.

Correlation between ECG and Cardiac Cycle
A cardiac action potential originates in the SA node and spreads throughout the atria and the AV node in approximately 0.03 seconds. This results in the P wave in an ECG and triggers atrial contraction. The action potential is then briefly slowed at the AV node, allowing the atria to contract and fill the ventricles with blood before...
Fetal Circulation
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
