Fetal heart abnormalities are the most common congenital anomalies and are also the leading cause of infant mortality related to birth defects. More than one-third of all malformations found after delivery are congenital heart defects. The prenatal detection of fetal cardiac structure is difficult because of its small size and rapid movements but is important for the early and effective diagnos...

Fetal arrythmia is reported to affect 1-2% of pregnancies. Besides digoxin not many drugs have been tried in treating such cases. After confirming 1:1 conduction between atrium and ventricle, no structural heart disease fetus normal echocardiography ECG mother, verapamil was given the treatment fetal supraventricular tachycardia. The drug crossed placenta revert SVT sinus rhythm without harming...

Objective This study aims to report our experience using the Monica AN24 (Monica Healthcare Ltd., Nottingham, United Kingdom), a maternal transabdominal fetal electrocardiographic monitor, in a case series of fetuses with arrhythmias. Study Design We recorded fetal electrocardiograms (fECGs) on subjects with fetal arrhythmias diagnosed by fetal echocardiogram. Fetal heart rate and rhythm were d...

BACKGROUND Relaxation-training, as an anxiety-reducer intervention, plays an important role in fetal health. The present study aimed to analyze the effect of maternal relaxation on stress test (NST), basal fetal heart rate, and number of fetal heart accelerations. METHODS In this randomized controlled trial, 84 pregnant women were randomly divided into two groups of teaching relaxation and co...

A1adenosine receptors (A1ARs) have been recently shown to be expressed in rodent embryonic hearts at very early stages of development. To determine the functional significance of fetal cardiac A1AR expression during embryogenesis, murine fetal heart preparations were studied between postconceptual days 9 and 12. Dose-response curves generated using a variety of adenosine agonists revealed that ...

MAR\~N L. MEITUS, M.D., P.C.C.P. Miami Beach, Florida THE FIRST FETAL ELECTROCARDIOGRAM in utero was obtained by Cremer,' in 1906. Of the clinical applications of fetal electrocardiography described in the literature, the following are included: 1. Confirmation of fetal life in utero. 2. Detection of early (first-trimester) pre.pancy. 3. Proof of multiple pregnancy. 4. Dia~pmis of fetal positio...

BACKGROUND Fetal electrocardiography is a developing field that provides valuable information on the fetal health during pregnancy. By early diagnosis and treatment of fetal heart problems, more survival chance is given to the infant. OBJECTIVE MATERIALS AND METHODS Here, we extract fetal ECG from maternal abdominal recordings and detect R-peaks in order to recognize fetal heart rate. On t...

OBJECTIVE To test the hypothesis that there are differences in the level of maternal-fetal attachment before and after fetal echocardiography in the presence or absence of cardiac abnormalities. STUDY DESIGN Cohort study in which the mothers responded to a validated Maternal-Fetal Attachment Scale. The study compared a group of pregnant women with diagnosis of fetal heart disease (FHD) with a...

1. The aim of this study was to define from umbilical artery flow velocity waveforms absolute peak systolic and time-averaged velocity, fetal heart rate, fetal heart rate variability and flow velocity variability, and the relation between fetal heart rate and velocity variables in early pregnancy.2.A total of 108 women presenting with a normal pregnancy from 10 to 20 weeks of gestation consente...

on scalp blood, such as measurement of lactate concentration, do not appear to improve diagnostic accuracy. Results of direct intrapartum monitoring of the neurological state of the fetus by electroencephalogram recordings'8 19 are difficult to interpret and once again probably identify only severe fetal distress. Against a background of slow technical progress there has been an increasing dema...
