Effects of oxymatrine on sodium current in isolated ventricular cells in guinea-pig / 吉林大学学报(医学版)

Objective:Effects of oxymatrine on the sodium current were studied .Methods:The whole cell voltage clamp technique was used in isolated ventricular cells of guinea-pig.Results:Oxymatrine (0.1,0.3 and 1 mmol/L) showed inhibition to the sodium current in dose-dependence.Conclusion:These results indicate that inhibition of oxymatrine to the sodium current may be one of mechanisms of its antiarrhythmic action.
