This is a pilot study utilizing trans-abdominal ECG and Doppler Ultrasounds to assess the feasibility of extracting fECGs in a volunteer population.


Inclusion Criteria: - Subjects must be pregnant women at least 18 years of age. - Subject's fetus must be between the gestational ages of 16 weeks and term. - Subjects must be able to tolerate 20 minutes (per fetus for which trans-abdominal ECG and Doppler ultrasounds will be performed) in the supine position. - Subjects are willing to provide informed consent and are willing to participate in all procedures necessary to complete the study. Exclusion Criteria: - Subjects must not have a physical or mental condition, in the opinion of the investigator, which will limit their ability to provide adequate consent.

Study Outcomes

Outcome Type:Primary Outcome
Measure:Beat-to-beat fetal heart rate will be compared to the Doppler result.
Time Frame:2 years
Safety Issues:False
Description:Beat-to-beat fetal heart rate will be compared to the Doppler result using Pearson Correlation. Timing of PR, QT, and QS, if visible, will be compared with published normative values from the neonatology literature as these values are not otherwise obtai
Outcome Type:Secondary Outcome
Measure:Evaluate the presence of other fECG intervals.
Time Frame:2 years
Safety Issues:False
Description:The fECG Separation Algorithm used in this research incorporates the filtering of noise of very high level as compared with the signal to be retrieved , in combination with employment of SVD (Singular Value Decomposition) methods.
