Figure 6
Incidence of ventricular tachyarrhythmias after β-adrenergic stimulation with isoproterenol (ISOP, 0.02 mg/kg) in HAB (n = 8).
The injection of ISOP was preceded by inhibition of FAAH activity with URB694 (URB, 0.3 mg/kg) or vehicle (VEH) administration. URB was administered in the presence of CB1 or CB2 receptor blockade with rimonabant (RIM, 2 mg/kg) or AM630 (2 mg/kg), respectively, or after VEH injection. Data are reported as means ± SEM of a 30-min time period. VEH+VEH+ISOP group served as control for VEH+URB+ISOP group. VEH+URB+ISOP group served as control for RIM+URB+ISOP and AM630+URB+ISOP group. Significant differences (p < 0.05): avs. VEH+VEH+ISOP group; bvs. VEH+URB+ISOP group.
