  • SYSTEMS AND METHODS FOR FETAL MONITORING
    Publication number: 20220125366
    Abstract: A system obtains a maternal electrocardiogram (ECG) signal that represents an ECG of a pregnant mother during a first time interval. The system further obtains a mixed maternal-fetal ECG signal that represents a combined ECG of the mother and her fetus during the first time interval; processes the maternal ECG signal and the mixed maternal-fetal ECG signal to generate a fetal ECG signal that represents the ECG of the fetus during the time interval, the fetal ECG signal substantially excluding the maternal ECG signal; and provides an output based on the fetal ECG signal.
    Type: Application
    Filed: January 7, 2022
    Publication date: April 28, 2022
    Inventors: Paul A. Friedman, Dorothy J. Ladewig, Itzhak Zachi Attia, Kyle D. Traynor

  • ECG-based analyte assessments with adjustments for variances in patient posture
    Patent number: 11191459
    Abstract: Systems, methods, and other techniques for estimating the level of an analyte present in a patient during a time interval using electrocardiogram (ECG) signals. The estimate can be improved using information about the patient's posture.
    Type: Grant
