Time series analysis of heart rate variability and heart rate dynamics from 24-h ECG-recordings using the following techniques: spectral analysis, nonlinear dynamics, information theory, combinatorics and the theory of African music. Furthermore, if heartbeat (ECG) and respiration (e.g. airflow via thermistor) are recorded simultaneously the cardiorespiratory interaction may be analyzed.

The goal is to investigate the processes of coordination and self-regulation (e.g. between heartbeat and respiration) in the human organism. The methods are applied to demonstrate the effects of remedies like Cardiodoron® and Atropa belladonna on cardiorespiratory control, and also to examine intra- and inter-individual physiological coordination in therapeutic processes like theapeutic speech or music therapy.

These investigations help to understand the physiological basis of how the organism manages to stay well. Furthermore, they help to understand the 'rhythmic system' as described by the anthroposophical view of man.
