Clinical Uses

Phenytoin, like lidocaine, is more effective in the treatment of ventricular than supraventricular arrhythmias. It is particularly effective in treating ventricular arrhythmias associated with digitalis toxicity, acute myo-cardial infarction, open-heart surgery, anesthesia, cardiac catheterization, cardioversion, and angiographic studies.
