The Effect of Procaine Amide (Pronestyl) in Clinical Auricular Fibrillation and Flutter

Abstract
Procaine amide (Pronestyl) was administered to patients with auricular fibrillation and flutter in an attempt to restore sinus rhythm. Thirteen of 20 patients with auricular fibrillation had sinus rhythm re-established. Several of the patients who were not converted with procaine amide were later restored to sinus rhythm with quinidine.
