Concerns about proarrhythmia risk and inefficacy associated with class I antiarrhythmic drugs have revived interest in low-dose amiodarone (maintenance dose 200–400 mg/day) for suppression of atrial fibrillation. In nonrandomized trials of amiodarone for atrial fibrillation refractory to conventional ...
An open, multi-centre study was carried out to assess the effectiveness and tolerability of amiodarone at a lower dose than routinely used in the clinical and symptomatic treatment of older patients with atrial fibrillation who were resistant to other therapy or in whom other therapy was either ...

importance for these patients. Treatment with AV node-blocking medications such as verapamil or digoxin can facilitate rapid conduction over the accessory pathway and result in ventricular fibrillation. When intravenous pharmacologic therapy is required, the drug of choice is procainamide or amiodarone. ...
A 60-year-old male patient complaining of palpitations, fatigue, weakness and weight loss of 1 month’s duration was hospitalized in our cardiology department for atrial fibrillation. Thyroid function test results were compatible with thyrotoxicosis. The patient had been taking amiodarone for 2.5 years...
For most patients, however, the most potent drugs for keeping the heart out of atrial fibrillation are the antiarrhythmic drugs, such as amiodarone. Although these drugs are generally effective at keeping the heart rhythm regular, they also can have serious side effects....
Do not take MULTAQ if: you have a certain type of heart problem called heart block, and you do not have an implanted pacemaker your heart rate is less than 50 beats each minute you have had liver or lung problems after using amiodarone ...
Miscellaneous anti-arrhythmia medications:These drugs control the heart rhythm rather than the rate. They reduce the frequency and duration of atrial fibrillation episodes. They are often given to prevent the return of atrial fibrillation after cardioversion. The most used drugs are amiodarone(Cordarone...
Drugs used in treating atrial fibrillation often have important side effects. Many patients discontinue them because they cannot tolerate these side effects. For example: Amiodarone commonly is used to treat atrial fibrillation because it is less proarrhythmic, and has been shown to maintain a normal...
