Values (means ± SD) are expressed in N/mm2 (n = 10). Ecirc, circumferential modulus; Erad, radial modulus; IVC, isovolumic contraction; IVR, isovolumic relaxation. Control data (CTRL_ESML and CTRL_STIM) were obtained immediately before esmolol and subthreshold electrical pulse stimulation interventions, respectively. A–H are column identifiers, and 1 and 2 are row identifiers. P < 0.001 [by 2-way repeated-measures ANOVA with Bonferroni's post hoc test (level of significance adjusted to P < 0.05/4)]:
