Atrial Fibrillation Treatment. Treatment for atrial fibrillation (AF) depends on how severe or frequent the symptoms are and whether you already have heart disease.Effectiveness of amiodarone and electrical cardioversion for chronic rheumatic atrial fibrillation after mitral valve surgery.Delayed Use Of Blood Thinners For Atrial Fibrillation Increases.Hershey Medical Center, Hershey, Pennsylvania Am Fam Physician.
Anticoagulant medicines, also called blood thinners, are recommended for most people with atrial fibrillation who are at average to high risk of stroke.It is often desirable to restore sinus rhythm in these patients.Background—In the treatment of patients with refractory atrial. cluded atrial fibrillation,.This can be accomplished using calcium channel blockers such as diltiazem (Cardizem) or verapamil (Calan, Isoptin), beta blockers such as metoprolol (Lopressor) or esmolol (Brevibloc), or digoxin (Lanoxin).The risk of proarrhythmia during DC cardioversion is very low.It is important to note that all methods of pharmacologic cardioversion are associated with proarrhythmic risks.
Although this method is safe and effective, it requires the placement of transvenous shocking coils into the right ventricle and the right atrium.Thus, if the refractory period of the atrial myocardium is short (i.e., faster recovery) or if the conduction time is so slow that the tissue can recover before the wavelet arrives, atrial fibrillation can develop.

Management includes heart rate control, rhythm control, anticoagulation therapy, or a combination of these strategies.

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.Atrial Fibrillation Medications. Medications for atrial fibrillation (AF or AFib) Medications are often prescribed.Comparison of intravenous ibutilide versus procainamide for the rapid termination of atrial fibrillation or flutter.Blood Pressure Lowering Treatment Trialists Collaboration. Automated measurement of office, home and ambulatory blood pressure in atrial fibrillation.Electrophysiologic mechanisms of perpetuation of atrial fibrillation.Atrial fibrillation is the most common sustained arrhythmia encountered in primary care practice.Cost-effectiveness of transesophageal echocardiographic-guided cardioversion: a decision analytic model for patients admitted to the hospital with atrial fibrillation.Pathophysiology Treatment of Acute Atrial Fibrillation: Rate and Rhythm Control Pharmacologic Methods of Ventricular Rate Control Pharmacologic Methods of Acute Cardioversion Final Comment References The acute management of atrial fibrillation depends on the patient and the clinical situation.

Unfortunately, it is not known whether restoration of sinus rhythm improves survival, reduces morbidity or even decreases the risk of embolic events. 5 Restoration and maintenance of sinus rhythm often require the use of antiarrhythmic medications that carry a risk of proarrhythmia.
Metoprolol (Lopressor) - Side Effects, Dosage
In hemodynamically stable patients, pharmacologic measures to control the heart rate, which may include intravenous or oral agents (or both), may be used.Care must be used in cardioversion, since all methods carry a significant risk of potentially lethal proarrhythmia.Prevalence of atrial fibrillation in elderly subjects (the Cardiovascular Health Study).
Previous: Intrauterine Growth Restriction: Identification and Management.Several pathophysiologic factors favor the initiation and maintenance of atrial fibrillation ( Table 1 ).Redefining the role of digoxin in the treatment of atrial fibrillation.Pharmacologic cardioversion using intravenous or oral class I or class III antiarrhythmic agents may be used instead of DC cardioversion.
Pathophysiology Treatment of Acute Atrial Fibrillation: Rate and Rhythm Control Pharmacologic Methods of Ventricular Rate Control Pharmacologic Methods of Acute Cardioversion Final Comment References Several pharmacologic agents may be used for acute cardioversion in patients with atrial fibrillation, including oral and intravenous medications.
Antiplatelet Therapy for Secondary Prevention of Stroke
The incidence of polymorphic ventricular tachycardia may be as high as 2 percent, even with the use of oral agents.External direct current (DC) cardioversion is the most effective means of converting atrial fibrillation to sinus rhythm.
In an outpatient clinic where intravenous administration of medications and electrocardiographic and blood pressure monitoring are available, the heart rate may be controlled initially with intravenous medications.Patients who are unstable (i.e., a heart rate of 150 or more with low blood pressure, angina pectoris, shortness of breath, decreased level of consciousness, shock, pulmonary congestion, congestive heart failure or acute myocardial infarction) during atrial fibrillation require immediate cardioversion using a 200-joule synchronized shock (preferably with effective conscious sedation).Rate-control medicines may relieve symptoms caused by the fast heart rate.
