Abstract

The evaluation of the Autonomic Nervous System (ANS) status can be performed by the measurement of the cardiac frequency variability, the variability of the QT segment and the dispersion of the QT segment. This paper presents the implementation of these estimations by means of Wavelet Transform-based algorithms and the Yule-Walker’s spectral estimation. Electrocardiographic records 20 minutes long were evaluated, having 15 minutes taken in a continuous way. Parameters of cardiac fuctuation were taken out from a population of 92 patients, who presented frst stroke and carried out with a strict inclusion protocol to evaluate their cardiac frequency variability. Statistical tests were performed to determine the repeatability of the measurements.
