Why the study?
Does non-invasive fetal electrocardiography allow for successful signal separation and establishment of cardiac time interval reference ranges in singleton and multiple pregnancies?
Population
304 pregnant women (241 uncomplicated singletons, 58 twins, 5 triplets) at 15-41 weeks of gestation

Non-invasive fetal ECG signal separation supports reference ranges in multiples; hypothesis-generating and should not yet change practice.
Does non-invasive fetal electrocardiography allow for successful signal separation and establishment of cardiac time interval reference ranges in singleton and multiple pregnancies?
Non-invasive fetal ECG is feasible across a wide gestational range in singleton and multiple pregnancies, enabling the establishment of reference ranges for fetal cardiac time intervals.
Taylor et al. (2003) studied this question.
