Fig. 2. Time course of force of contraction (FoC; expressed as percent of baseline) of isolated human right atrial trabeculae in the control (n = 10), 3% desflurane (n = 6), 6% desflurane (n = 6), and 9% desflurane (n = 9) groups. Data are mean ± SD. NS = not significant.  P < 0.0001 denotes between-groups analysis of variance. *  P < 0.0001  versus baseline for all groups. #  P < 0.0001  versus baseline and 3%, 6%, and 9% desflurane groups.
