Most fetal heart rate patterns can be interpreted accurately so that management decisions can be made correctly. How-ever, few fetal heart rate patterns are so ambiguous that the obstetricians cannot interpret them precisely. A 27-year-old woman at 38 weeks' gestation in her first pregnancy was admitted with heavy vaginal bleeding and decrease in fetal movements. Fetal status was indeterminate ...

OBJECTIVE To evaluate fetal cardiac response to cordocentesis and whether such changes may affect pregnancy outcome. METHODS 117 singleton pregnant women requiring percutaneous trans-abdominal cordocentesis were prospectively included. Fetal heart rate was continuously evaluated by ultrasound for 1 min after completion of cordocentesis and intermittently for 20 min more. Fetal and pregnancy o...

Electronic Fetal Heart Rate (FHR) monitoring is recommended to assess fetal well-being during labour in high risk pregnancies. This Cardiotocograph (CTG) relies on the ultrasound technology with limitation of signal loss 15% 40% cases [1]. In earlier versions these CTG monitors, heart tracings were generally reasonable quality many artefacts and some degree occasional large noise. Subsequent mo...

Recent advances in echocardiography have allowed the anatomical structure of the fetal heart to be successfully and safely seen in details. It has since enabled not only the prenatal diagnosis of congenital heart disease but the diagnosis and treatment of fetal arrhythmias. New advances of Doppler echocardiography have provided exciting informations on the fetal physiology of normal or abnormal...

the increasing processes of body and heart weight, the index changes of heart to body weight ratio and of heart walls thickness (ventricular and inter ventricular) were studied on 160 goat fetuses (2groups male and female) from 7 to 22 week ages (at the first to the end of fetal period). data analysis in spss and by anov a showed that the influence of age in all of 6 studied parameters was sign...

Aims: To precisely diagnose Fetal Heart Rate (FHR) with actocardiogram (ACG), which is the simultaneous record of FHR and movement signal spikes. Method: Low frequency ultrasonic Doppler signal of fetal movement and high frequency Doppler of fetal heart beat were detected with single ultrasonic probe, and separated into two groups by a new electric circuit. FHR was recorded by autocorrelation h...
