Figure 7From: A multivariate time-frequency method to characterize the influence of respiration over heart period and arterial pressureResults from autonomic blockade experiment. Circles represent the median value of a given index from a single subject, I (m) ( s ) . Crosses represent the median of I (m) ( s ) . On the left: comparison between indices from control condition and after atropine injection. On the right: comparison between indices from control condition and after propranolol injection. Dashed line in (a), (b) represent the mean value of the threshold function used to assess the significance of coherence estimatesBack to article page
