[Deterministic-chaotic and spectral-functional analysis of heart rate and respiratory movements].

After an introduction into the analysis of periodical-linear and deterministic- chaotic characteristics of heart rate fluctuations and respiratory movements their physiological background and clinical aspects are debated. Using the example of own results at the mature rabbit and new-born pig different relations of periodical-linear and deterministic-chaotic characteristics in dependence on the experimental status and neurovegetative blockades are demonstrated. From the data assignments of these characteristics are derived.
