Acute Conversion of Recent-Onset Atrial Fibrillation and Flutter: Class IC or Class III Drugs?usion when it comes to evaluating the efficacy of an antiarrhythmic regimen. In any case, the longer the arrhythmia continues, the less likely is its conversion into sinus rhythm, because of the electric remodeling of the atria (shortening of the refractory period) caused by the persistent fibrillat

The efficacy of the procedure mainly depends on atrial fibrillation duration and left atrial size. The success rate is about 90% in patients with atrial fibrillation duration of less than 1 year and 50% in patients with atrial fibrillation of 5 years duration [3]. Also

Drug Prevention of Atrial Fibrillation: Are Novel Agents More Effective Than the Old Ones? By contrast, persistent AF does not self-terminate and needs electrical cardioversion for restoration of sinus rhythm [1]. Cardioversion for persistent AF is in general successful. However, the Achilles’ heel in the treatment of both paroxysmal and persistent AF is arrhythmia recurrence. It should

Implantable Atrial Defibrillator: What are the Results of Initial Experience?osts [1, 2]. The limited efficacy and the side effects of drugs used both to maintain sinus rhythm and to control the heart rate have increased interest in the development of non-pharmacological therapy for AF [3]. The implantable atrial defibrillator (IAD) is one such therapeutic tool.
