Figure 7. Comparison of the effects of halothane and isoflurane on isometric active force (AF) normalized per cross-sectional area of papillary muscles from healthy hamsters and those with cardiomyopathy. Halothane and isoflurane concentrations are reported as minimum alveolar concentration multiples in each strain. Data are mean +/- SD. Probability values refer to between-group difference (multivariate analysis of variance). NS = not significant. *P < 0.05 versus control values.
