Key result
Prophylactic antiarrhythmic drugs are utilized to maintain sinus rhythm and manage the high relapse rate following electroconversion of atrial fibrillation.
Why the study?
Do antiarrhythmic drugs maintain sinus rhythm after electroconversion in patients with atrial fibrillation?
Do antiarrhythmic drugs maintain sinus rhythm after electroconversion in patients with atrial fibrillation?
This review discusses the use of antiarrhythmic drugs to maintain sinus rhythm following electroconversion for atrial fibrillation and proposes a treatment strategy.
May inform post-cardioversion rhythm strategies; leaves open optimal drug selection and contemporary outcomes.
Atrial fibrillation is a common arrhythmia. Sinus rhythm can often be restored by electroconversion, but the relapse rate is high. Various antiarrhythmic drugs have been used to maintain sinus rhythm after electroconversion. This article reviews the experience with these drugs and suggests a treatment strategy.
