title: Fetal arrhythmia during pregnancy and labour.
abstract: The significance of fetal arrhythmia presenting during pregnancy and labour has been examined in 68 patients. The different types of rhythm disorders diagnosed included 61 extrasystoles, 6 atrioventricular blocks and 1 auricular fibrillation. Extrasystoles were not associated with acidosis or organic cardiac disease. Atrioventricular block, though not associated with fetal hypoxia, was occasionally associated with congenital cardiac failure.
