Differential effects of class I antiarrhythmic drugs on the guinea pig pulmonary vein myocardium: Inhibition of automatic activity correlates with blockade of a diastolic sodium current component

The effects of class I antiarrhythmic drugs on the automaticity of isolated guinea pig pulmonary vein myocardia were investigated using microelectrode and voltage clamp methods. All of the drugs examined reduced the maximum rate of rise of automatic action potentials. The firing frequency and rate o...
