Differences in frequencies indicate detected heart motion. Periodicity of the motion is displayed as heart rate. This rate is printed on a strip-chart recorder. At the same time, uterine activity is typically detected, also indirectly, by a transducer (i.e., tocodynamometer), which is applied...
Summary Over the past 30 years, electronic fetal heart rate monitoring has become an accepted means of assessing fetal status during labor. More than 85% of livebirths in the USA are so monitored despite a frequent lack of agreement on strip interpretation and management decisions. This has resu...
Fetal heart rate (FHR) deceleration areas were studied to obtain by objective measurement of the FHR, their prognostic value of the new-born state. 1. There is a reasonably good correlation between FHR deceleration areas and UApH (Tab. II). Such a correlation was found by SHELLEY and ...
practice to run a strip of cardiotocograph prior to commencing oxytocin to make sure of good fetal health as reflected by a normal reactive FHR pattern:if the trace is pathological then oxytocin should not be used, as it can cause further hypoxia to the fetus by reducing the perfusion to ...
“strip” or “print-out” recording of the heart rate. There was a low rate of obstetric malpractice, because there were no records to challenge the hospital’s side of the story. After EFM, physicians relied on the new EFM recordings as their defense against cerebral palsy lawsuits. ...
either systole or diastole. An example of such simple method would be to put the values of the incoming data stream to zero for a defined time after detection of a heart activity. In practice, however, the recorded echo signals are so weak and hidden in the noise that a peak trigger me...
Fetal Heart Rate In contemporary practice, continuous intrapartum assessment of FHR by external monitoring involves the use of a continuous-wave Doppler ultrasound device. The Doppler ultrasound transducer is empirically located on the maternal abdomen at the site where the fetal cardiac motion is most...
1 seem to be sensitive and specific; however, evidence is lacking especially in equivocal cases and comparative studies against the real gold standard (amnio-dye) have still not been published. The authors stated that further effectiveness research is needed before tests can be applied in practice...
