Clinical Use of Antiarrhythmic Drugs

Abstract
Fundamental to treatment of cardiac arrhythmias are a precise diagnosis of the rhythm abnormality, knowledge of its natural history, and understanding of the cardiac effects of the antiarrhythmic drugs. The mechanisms of most arrhythmias are as yet undefined. Quinidine, procaine amide, propranolol, diphenylhydantoin and lidocaine are the commonly used antiarrhythmic drugs.
