Objective To investigate the effect of Dang Gui Ke Li(DGKL)on experimental arrhythmia induced by calcium chloride(CaCl2).Methods Arrhythmic models induced by CaCl2 in rats were used to study the effect of DGKL on experimental arrhythmia.Results DGKL(1.35,2.70,5.40 g/kg)decreased the incidence and mortality of arrhythmia,delayed the emergence time and shorted the duration of arrhythmia in rats induced by CaCl2 in a concentration-dependent manner.Conclusion DGKL has a significantly protective and preventive e...
