本实验分别采用药物、手术及电刺激诱发心律失常模型及应用先进的膜片钳等技术研究我室首创的新药黄谷素的药效。结果发现，此药对各种心律失常模型均有对抗作用，且具有低毒、疗效确切等特点。其药效与已知抗心律失常药奎尼丁、胺碘酮相当，其作用原理为抑制外向Ｋ电流和尾电流。 In this experiment, drug, surgery and electrical stimulation-induced arrhythmia model and the application of advanced patch clamp and other techniques to study our room of the first new drug efficacy of yellow pigment. The results showed that the drug has a variety of arrhythmia models have antagonistic effects, and has low toxicity, the exact effect and so on. Its efficacy and known anti-arrhythmic drugs quinidine, amiodarone quite, its principle of action to inhibit the outward K current and tail current.
