Resumen
Fetal hypoxia/acidemia recognition improves with computerized analysis of biosignals collected from cardiotocography (CTG), particularly the assesment of short-term variability (STV) of fetal heart rate (FHR). Several methods to compute STV have been described with varied performance results according to acquisition method, sampling and storage rates and algorithm definition. Dawes-Redman algorithm (STV16) is the most widely reproduced in available commercial systems. However, it shows a low correlation with the beat-to-beat variation determined from fetal electrocardiographic signal (fECG). STV240 algorithm has been introduced in an attempt to approximate STV assessment to real beat-to-beat variation. There is no comparison in the literature between these two algorithms, taking as gold standard variability obtained from ECG tracing. With a view to providing reliable records for the standardization and comparison of STV algorithms, most notably, STV16 and ...
