Objective To observe the effect of different-frequency-electroacupuncture(EA)and moxibustion stimulation on rabbits' arrhythmias.Methods Newzealand rabbits were randomly divided into arrhythmia model(n=18)

EA-3Hz(n=19)

EA-20Hz(n=19)

EA-100Hz(n=18)and moxibustion(n=18)groups.The arrhythmia model was induced by intravenous injection of 25μg/kg aconitine.EA(3Hz

20 Hz or 100 Hz

3.5-4V)or moxibustion was applied to bilateral"Neiguan"(PC 6)for 20 min and electrocardiogram(ECG)of the standard limb leadⅡ was recorded by using a Biosignal Processing Instrument.The concentration of serum hypersensitive C reactive protein(hs-CRP)content was detected by using ELISA method.Results Following EA intervention

the duration of aconitine-induced arrhythmia was significantly shorter in both EA-20 Hz and EA-100 Hz groups than in the model group(P<0.05

P<0.01)

and the serum hs-CRP level in the EA-20 Hz group was significantly lower than that of the model group(P<0.05).No significant changes were found in the duration of arrhythmia in both EA-3Hz and moxibustion groups

and in the serum hs-CRP level in the EA-3Hz

EA-100 Hz and the moxibustion groups(P>0.05).Conclusion EA stimulation of PC 6at 20 Hz and 100 Hz has an anti-arrhythmic effect in aconitine-induced arrhythmia rabbits.
