Effect of oral administration of oleuropein (20 mg/Kg) for several days against aconitine-induced arrhythmia in rats. A: The initiation time of arrhythmia; B: The initiation time of ventricular tachycardia (VT); C: The episodes of ventricular ectopic beats before VT incidence; D: The number of reversible ventricular fibrillation (VF); E: The death time. Con: control group; O3, O7, O14 and O28: mean groups that received oleuropein for 3, 7, 14 and 28 days before the infusion of aconitine (0.2 μg/min), respectively. *: p < 0.05 vs Con group
