Computerized algorithm for fetal heart rate baseline and baseline variability estimation based on distance between signal average and α value

Abstract

This study proposed new algorithm for FHR baseline (BL) and baseline Variability (V) calculation. In this study, we present a method for estimating baseline as one of the most important features present in the (FHR) signal. An algorithm based on digital (CTG) using Math Lab programming to estimate FHR baseline and baseline variability, the research in this study rely on detection of baseline value and baseline variability which gives an indication of the fetal status and health condition. The results are compared with the opinion of experts (obstetricians) baseline and baseline variability estimation. The obtained results shows slightly difference with the expert's opinion as a first step for further work to estimate the other parameters of the CTG. © 2011 Asian Network for Scientific Information.
