[Protective effect of Angelica injection on arrhythmia during myocardial ischemia reperfusion in rat].

The protective effects of Angelica injection on arrhythmia were studied through the model of ischemic myocardial reperfusion in rats. The results showed that the incidence of ventricular premature beat and the total incidence of arrhythmia (IA) were greatly reduced by peritoneal injection of Angelica (0.6 gm crude drug/kg) in rats. The difference between the Angelica group (n = 12, IA = 41.7%) and the saline control group (n = 12, IA = 91.7%) was significant (P less than 0.05), while that between Angelica group and verapamil group (n = 10, IA = 40%) was insignificant (P greater than 0.05). The data suggested that Angelica injection is effective on the protection of arrhythmia during the myocardial ischemia reperfusion in rats.
