Key result
Commonly used antiarrhythmic drugs like quinidine, procaine amide, propranolol, diphenylhydantoin, and lidocaine require precise diagnosis and understanding of their cardiac effects.
Provides a general overview of the clinical use of common antiarrhythmic drugs for cardiac arrhythmias.
Requires precise arrhythmia diagnosis before antiarrhythmic selection; leaves mechanisms of most rhythms incompletely understood.
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.
