[Drug therapy of tachycardial arrhythmias]

In recent years the antiarrhythmic armamentarium has been widened by several new drugs. The effects and side effects of amiodarone, verapamil, prenylamine and prajmalium bitartrate are described. With the introduction of the newer drugs, new recommendations have to some extent emerged with regard to treatment of tachyarrhythmias. For a national understanding of antiarrhythmic agents, regard must be had to their effects on both normal and damaged cells.
