to what degree best to manage nonvalvular atrial fibrillation is controversial. the same option is restoring normal sinus metre through antiarrhythmic medications and cardioversion. The verse control method relieves symptoms and delays or obstructs chronic atrial fibrillation. However, and nothing else approximately 50 percent of patients who receive this treatment have a normal sinus verse after six months to single year, and the strategy for preventing thromboembolic adventures has not been established. The other option is rate superintendence which is easier to achieve than verse control and improves hemodynamics. The disadvantage is that it allows atrial fibrillation to persist and may not relieve its symptoms. Opolski and associates compared the risks and benefits of rate check versus rhythm control in patients with atrial fibrillation.

This prospective, randomized, spread multicenter clinical trial involved six cardiology center Participants were 50 to 75 years of age and had between seven days and pair years of persistent atrial fibrillation. Exclusion criteria were extensive and included documented inefficiency, intolerance to or contraindications to antiarrhythmic medications, and an identifiable reversible cause for atrial fibrillation. Participants were randomized to receive rate or number control treatments. Rate control was achieved by the and of rate-slowing therapies, and the effectiveness was assessed using repeat 24-hour Holter monitors. The periodical emphasis control group received serial cardioversion and antiarrhythmic medications (the specific medication varied among patients) using a stepwise protocol. the pair groups received anticoagulation following the established guidelines. Main issue measures were death from any cause, thromboembolic complications, and intracranial or other major hemorrhage.

The meditation involved 205 patients (101 in the rate sway group and 104 in the rhyme control group). The mean observation period for the cogitation was 1.7 years. At the last of this period, 63.5 percent of patients in the verse control group remained in sinus regular [i]or[/i] melodious movement The two groups, however, did not point out significantly different main outcomes. The incidence of hospitalization was significantly lower in the rate rule group compared with the periodical emphasis control group. Both groups showed improvement in their modern York Heart Association functional class. The harmonious flow control group had a significant improvement in exercise tolerance compared with the rate reign over group.

The authors judge that there are no significant differences in major conclusion points between rate control and harmonious flow control treatment of chronic atrial fibrillation. They add that physicians should base their choice of therapy in succession the individual patient's needs.
