Beat rate variability analysis with combined salbutamol and aminophylline treatments. Scatter plots indicate means and SDs of SDSDs measured with mixed treatments and control (n = 10 for controls, n = 10, 11, 10, 8, 8, 24, 6, 6, and 9 for treatments, p values in Table S1 in Supplementary data, Ordinary one way ANOVA test was used). (A) SDSD results of EBs with indicated concentrations of salbutamol and aminophylline supplemented with separate measurements of both treatments for comparison. The results of the mixes consist of two separate experiments, so the same control dataset was used based on time of measurement (the first two controls are the same as the third and fourth, relating to 20 min and 40 min of treatment). The results of separate aminophylline administration originate from our previous paper6. (B) Poincaré plots with SDSD intervals.
