Basal measurements from the right ventricle strips.

<p>The effect of myocardial infarction in rats with continuous exposure to HgCl₂ on the basal conditions of isometric force (A), time to peak tension (B), relaxation time to 90% (C), +dF/dt (D) and −dF/dt (E) of rat right ventricular strips from the Control, MI and HgCl₂-MI groups. The results are reported as the means ± SEM for 10–12 animals per group. MI = myocardial infarction; dF/dt = time derivatives of right ventricular force development. *P<0.05 <i>vs</i> Control and HgCl₂-MI; # P<0.05 <i>vs</i> Control (one-way ANOVA followed by Tukey's <i>post hoc</i> tests).
