Phase-rectified signal averaging: correlation between two monitors and relationship with short-term variation of fetal heart rate.

PRSA appears to be equivalent method of fetal assessment to STV, but due to its innate ability to eliminate artefact, PRSA is superior to STV in generating interpretable traces and trace accuracy with NIFECG. These findings raise the possibility of self-applied home or remote fetal heart-rate monitoring with automated reporting to enable increased surveillance in high-risk women without impacting service demand.
