Phenytoin
Phenytoin is a potent medication to treat central nervous system seizures, but its antiarrhythmic actions are limited. It effectively abolishes abnormal automaticity caused by digitalis toxicity. Sinus nodal automaticity and AV conduction are only minimallly affected by phenytoin. Pheny-toin’s electrophysiological effects in vitro appear similar to those of lidocaine. It exerts minimal hemodynamic effects. Phenytoin may be successful in treating atrial and ventricular arrhythmias due to digitalis toxicity but is much less effective in treating arrhythmias of other etiologies.
