In order to relate the cardiac antiarrhytmic properties of magnesium chloride (MgCl2) to its electrophysiological effects, a comparison of its actions on three different models of automaticity of the isolated Purkinje fibers of the dog, has been carried out. The spontaneous activity of the Purkinje fibers perfused with Tyrode's solution containing 2.7 mM(More)
We compared the electrophysiological effects of lidocaine, l-chlorpheniramine, and bepridil on rabbit sinus node pacemaker cells. Only bepridil (0.25-2.0 mg/L) caused a marked reduction in the automaticity of the sinus node. Action potential amplitude, overshoot, and maximum rate of depolarization of phase O (MRD) were all reduced in a dose-dependent manner(More)
We compared the electrophysiological effects of lidocaine, l-chlorpheniramine, and bepridil on both normal and ouabain-induced automaticity of canine Purkinje fibers. All three drugs suppressed the automaticity of spontaneously beating Purkinje fibers, but only lidocaine and bepridil reduced the amplitude of delayed afterdepolarizations induced by ouabain.(More)
