Until the results of several large-scale randomized clinical trials are available, the decision to choose cardioversion or maintenance of sinus rhythm must be individualized, based on relief of symptoms and reduction of the morbidity and mortality associated with atrial fibrillation.WOLBRETTE, M.D., is assistant professor of medicine and director of cardiac pacing and electrocardiography at the Milton S.Effectiveness of amiodarone and electrical cardioversion for chronic rheumatic atrial fibrillation after mitral valve surgery.
Cardioversion vs. Catheter Ablation for Persistent Atrial
Thus, it is often difficult to estimate the onset, duration or severity of atrial fibrillation by the history alone.Medications for atrial fibrillation (AF or AFib) Medications are.

Oral propafenone to convert recent-onset atrial fibrillation in patients with and without underlying heart disease.
But these medicines may not relieve other symptoms caused by atrial fibrillation.It is estimated that the annual risk of stroke in patients with atrial fibrillation is as high as 4.5 percent. 3 Atrial fibrillation also can decrease exercise tolerance and has been associated with tachycardia-induced cardiomyopathy.

Up to 70 percent of all conversions occur within 20 minutes of infusion. 34, 35 If the first dose is ineffective, a second may be administered before alternative strategies are considered.Permanent atrial fibrillation is refractory to attempts at cardioversion.Other methods of pharmacologic and nonpharmacologic cardioversion remain under development.Reducing how often a patient receives amiodarone, a medication used for suppressing atrial fibrillation (irregular heart beat) but which causes side effects, did not.

Furthermore, the electrophysiologic effects of ibutilide are maintained at fast heart rates.Antiarrhythmic medications may be of benefit by prolonging the refractory period of atrial tissue, thus preventing propagation of multiple reentry wavelets in the atria.
In patients with persistent atrial fibrillation, several intravenous and oral pharmacologic alternatives to DC cardioversion are available.
Atrial fibrillation from A to Z - Qardio Healthy Heart Blog
Although many patients with atrial fibrillation are symptomatic, some patients remain asymptomatic.Thus, cardioversion is used only in cases of acute and chronic persistent atrial fibrillation and not in cases previously demonstrated to be refractory.
Atrial Fibrillation Treatment in Stable Patients - Atrial
Ibutilide has little to no effect on the conduction velocity of the atrial tissue. 33 The electrophysiologic actions of ibutilide make it difficult for the atrial tissue to support multiple wavelets of reentry.If atrial fibrillation has been present for more than 48 hours or if the onset is unknown, an initial three- to six-week course of anticoagulation is recommended.Arrhythmia - Information and Treatment.
