Fetal arrhythmia during pregnancy and labour
British Journal of Obstetrics and Gynaecology
|July 1, 1977
Summary
Fetal arrhythmia during pregnancy, including extrasystoles and atrioventricular blocks, was studied in 68 patients. While extrasystoles showed no adverse associations, atrioventricular blocks were occasionally linked to congenital cardiac failure.
Area of Science:
- Obstetrics and Gynecology
- Fetal Medicine
- Cardiology
Background:
- Fetal arrhythmia is a significant concern during pregnancy and labor.
- Understanding the implications of different fetal heart rhythm disorders is crucial for perinatal care.
Purpose of the Study:
- To examine the significance of fetal arrhythmia presenting during pregnancy and labor.
- To identify the types of rhythm disorders and their associated conditions.
Main Methods:
- Study included 68 patients presenting with fetal arrhythmia.
- Diagnosis of rhythm disorders included extrasystoles, atrioventricular blocks, and auricular fibrillation.
Main Results:
- The study identified 61 cases of extrasystoles, 6 of atrioventricular blocks, and 1 of auricular fibrillation.
- Extrasystoles were not associated with acidosis or organic cardiac disease.
- Atrioventricular block was not linked to fetal hypoxia but was occasionally associated with congenital cardiac failure.
Conclusions:
- Fetal extrasystoles generally have a benign prognosis.
- Atrioventricular block in fetuses requires careful monitoring due to potential association with congenital cardiac failure.
