INFLUENCES OF PERFUSATE ION CONCENTRATION ON REPERFUSION ARRHYTHMIAS IN LANGENDORFF HEART OF RATS / 中国药理学通报

Using method of orthogonal design we observed that low K+,high Ca2+ & low Mg2+ in perfusate produced the peak incidence of reperf-usion-indaced ventricular fibrillation & introduction of K+ & Ca2+ significantly affected the incidence & pnset of it, The appropriate prop-ortion of K+, ea2+ & Mg2+ in perfusate is the important effecting factor of reperfusion-induced arrhythmias in Langendorff heart of rats.
