Key result
A standardized 12-lead fetal electrocardiogram was successfully recorded in 98.3% of healthy mid-pregnancy fetuses, revealing a right inferiorly oriented median electrical heart axis.
Why the study?
Mid-pregnancy fetal heart ultrasound is highly dependent on operator skill, fetal position, and maternal BMI, making an additional, less experience-dependent tool such as fetal ECG desirable.
Is it feasible to record a standardized 12-lead fetal ECG in mid-pregnancy to assess the fetal heart and detect congenital heart disease?
Population

Is it feasible to record a standardized 12-lead fetal ECG in mid-pregnancy to assess the fetal heart and detect congenital heart disease?
Non-invasive standardized 12-lead fetal electrocardiography is highly feasible in mid-pregnancy and may serve as a valuable adjunct to ultrasound for detecting congenital heart disease.
Lempersz et al. (2020) conducted a cross-sectional in Healthy fetus in mid-pregnancy (n=328). Standardized 12-lead fetal electrocardiogram was evaluated on Feasibility of recording a standardized fetal ECG and determining median ECG waveform. A standardized 12-lead fetal electrocardiogram was successfully recorded in 98.3% of healthy mid-pregnancy fetuses, revealing a right inferiorly oriented median electrical heart axis.
