TLDR
Software for FHR assessment from phonocardiography, a passive and low cost acoustic recording of fetal heart sounds, seemed to be satisfying, as provided FHR series were almost all confined within FHR-CTG +/- 3 bpm.Abstract:
A valuable alternative to US cardiotocography, for fetal surveillance, can be offered by phonocardiography, a passive and low cost acoustic recording of fetal heart sounds. A crucial point is the exact recognizing of the fetal heart sounds, associated to each fetal heart beat, and then the estimation of FHR signal. In this work, software for FHR assessment from phonocardiographic signals was developed. To check the reliability of the software, obtained results were compared with those of simultaneously recorded cardiotocographic signals. Results seemed to be satisfying, as provided FHR series were almost all confined within FHR-CTG +/- 3 bpm, where FHR-CTG were FHR series provided by commercial US cardiotocographic devices, currently employed in clinical routine.read more

A rule-based phonocardiographic method for long-term fetal heart rate monitoring
F. Kovacs,M. Torok,I. Habermajer +2 more
TL;DR: A real-time method for fetal heart rate monitoring based on signal processing of the fetal heart sounds is presented, and a large number of clinical tests have shown the very good performance of the phonocardiographic method in comparison with FHR curves simultaneously recorded with ultrasound cardiotocography.

An advanced method in fetal phonocardiography
TL;DR: A novel two-channel phonocardiographic device and an advanced signal processing method for determination of the FHR provided 83% accuracy compared to the simultaneously recorded reference ultrasound measurements.

2 Developments in CTG analysis
TL;DR: There is a need for quantitative and objective FHR analysis, as long as it does not lead to erroneous results, and there is still a long way to go until decision support systems find their way into obstetric practice.

Foetal heart rate power spectrum response to uterine contraction
TL;DR: Modifications of the power spectrum of FHR variability corresponding to UC can potentially reveal autonomic nervous system activity of the foetus and, therefore, additional, objective information about foetal reactivity during labour.
