Echocardiography and fetal heart sounds in the diagnosis of fetal heart block
American Heart Journal, 1979A 32-week fetus was demonstrated phonocardiographically and echocardiographically to have a regular atrial rate of 150 per minute and a regular ventricular rate of 39 per minute, indicating complete heart block. The diagnosis was suspected when two groups of heart sounds at two distinct rates were heard on auscultation, and was confirmed by the ...

FETAL HEART RATE RESPONSES TO FETAL MOVEMENTS
BJOG: An International Journal of Obstetrics & Gynaecology, 1977SummaryA classification of fetal heart rate (FHR) responses to fetal movements is based on the study of 210 hours of antepartum cardiotocographic tracings in clinically normal pregnant patients between 30 and 42 weeks gestation. The physiological mechanisms underlying the FHR responses to fetal movement are discussed.

Fetal congestive heart failure
Seminars in Fetal and Neonatal Medicine, 2005Fetal echocardiography is used in the diagnosis of many forms of congenital heart disease, and in the assessment of the prognosis of cardiac lesions based on their anatomy and presentation in utero. However, the presence of signs of fetal heart failure such as hydrops or valvular regurgitation makes the assessment of prognosis more difficult.

Activation of the human fetal heart
American Heart Journal, 1973Abstract Epicardial activation of atrial and ventricles, endocardial activation of the ventricles, and intramural activation of the interventricular septum, were studied in 11 isolated, revived, and perfused human fetal hearts. No evidence was found for specialized pathways in the atria.

Journal of Magnetic Resonance Imaging, 2019
In the last decade, technological advances have enabled the acquisition of high spatial and temporal resolution cardiac magnetic resonance imaging (MRI) in the fetus. Fetal cardiac MRI has emerged as an alternative to ultrasound, which may be helpful to confirm a diagnosis of congenital heart disease when ultrasound assessment is hampered, for example ...

The Fetal Heart in Diaphragmatic Hernia
Clinics in Perinatology, 1996Cardiac evaluation is an important part of the investigation of a fetus with a diaphragmatic hernia. The heart is displaced by the physical presence of the abdominal contents in the chest, and the flow dynamics within the heart are altered. This can produce secondary diminution of chamber growth, particularly of the left heart.

Doppler in Fetal Heart Failure
Clinical Obstetrics & Gynecology, 2010Fetal echocardiography has progressed to be able to diagnose many forms of congenital heart disease (CHD) and to assess the prognosis of cardiac lesions based on their anatomy and presentation in utero. Fetal echocardiography is for pregnancies at risk of structural, functional, and rhythm-related fetal heart disease.

European Journal of Obstetrics & Gynecology and Reproductive Biology, 1983
Two cases with sinusoidal fetal heart rates (SHR) with good perinatal outcome are reported. Since nonstress tests, oxytocin challenge tests and serum free estriols were normal, SHR was considered not indicative of fetal compromise. A SHR can occasionally be found in connection with reactive nonstress test.

Catecholamines in human fetal heart
Experientia, 1974In 4 fotalen menschlichen Herzen im Alter von 10–16 Wochen fanden sich wohl intrazellulare Katecholamine, hingegen keine adrenergischen Nervenendigungen. Das fotale Herz durfte somit zumindest im Beginn seines Lebens adrenergisch gesteuert sein.

Clinical Obstetrics & Gynecology, 2012
The majority of children born with congenital heart disease have no identifiable risk factors and, therefore, prenatal diagnosis relies on routine ultrasonographic screening. First proposed in 1985, the 4-chamber view is a component of the basic fetal cardiac examination.
