Abstract
Heart rate variability (HRV) is an important marker for fetal well-being. Various methods have been used to analyse HRV, in particular parameters from the time and frequency domain [1]. Recently mathematical methods have been introduced which go beyond the examination of overall variance or rhythmic changes in heart rate [2,3]. The goal is to quantify temporal complexity by examining the chaoticity of time series in a reconstructed State space. These methods can be applied to fetal heart period time series to examine whether irregulär but typical nonlinear dynamical heart rate patterns can be identified. These patterns might then be linked to fetal well-being.
