An intelligent quantification system for fetal heart rhythm assessment: A multicenter prospective study
Authors' conclusion
Using our HR-IQS is feasible for the automated calculation of CTIs in practice and thus could provide a promising tool for the assessment of fetal rhythm and function.
Study context
- Population
- Fetuses with pulsed-wave Doppler (PWD) spectrums over the junction between the LV inflow and outflow tracts6,498 PWD spectrums
- Participants
- 2,630 fetuses
- Exposure
- Heart rhythm intelligent quantification system (HR-IQS) automated vs manual measurement of fetal cardiac time intervals (CTIs)
- Outcome
- Agreement between manual and HR-IQS-based CTI values; normal reference range of 17 fetal CTIs

Main finding
As reported in the abstract
Agreement of HR-IQS vs manual CTI measurements
- Significant positive correlation between manual and HR-IQS measurements
- P <.001
- Moderate-to-excellent consistency between manual and HR-IQS measurements
- P <.001
Observational data: associations, not effects.
Further findings
- Non-normal distribution of CTIs
- P < 0.001
