Phenytoin sketchy.
Class 1 antiarrhythmics inhibit the fast Na channels in non-nodal myocardial tissues and are subdivided into 3 categories (A, B, and C) on the basis of their speed of dissociation from the Na channels and electrophysiologic effects. All drugs in class 1 reduce cardiac conduction velocity to some degree by slowing phase 0 depolarization.
Class IB antiarrhythmics, represented by agents like lidocaine, mexiletine, and to some extent, phenytoin, possess a low affinity for sodium channels. This results in only a modest reduction in the phase 0 upstroke speed. Phenytoin is a long-standing, anti-seizure drug widely used in clinical practice.
