Fig. 2From: Eurythmy therapy increases specific oscillations of heart rate variabilityExamples of RR-interval time series during a EYT-A (‘I Think The Saying’) and b EYT-B (‘Migraine B’) obtained from one subject. In this example, EYT-A was repeated 11 times and EYT-B was repeated 12 times during 8 min. Each repetition of the sequence of movements is indicated by the dashed lines. During ‘I Think The Saying’ a lengthening of RR-intervals occurs at regular intervals whereas during ‘Migraine B’ a pronounced oscillation occurs in the RR-interval seriesBack to article page
