[Fetal systolic time intervals. A non-invasive parameter for assessing the intrauterine condition of the fetus].
Various methods are employed in obstetric prophylaxis and treatment to assess the intrauterine condition of the foetus. The systolic time-intervals appear to be a promising new method because they reflect the contractility of the foetal heart which is a reflection of various physiological factors indluding hypoxia and asphyxia. Monitoring of the foetal systolic time intervals is therefore a more sensitive parameter of cardiac function than the foetal heart rate alone. By measurement of the foetal systolic time-intervals, it is therefore theoretically possible to evaluate the intrauterine situation of the foetus as abbreviated pre-exjection time (PEP) is a normal physiological reaction to scalp compressions, uterine contractions, or umbilical cord complications. Finally, the relationship between PEP and the ejection time (PEP/VET) is raised in asphyxia and greatly raised in imminent foetal death.
