This clinical trial is focused on studying a condition known as Atrial Fibrillation (AF), which is a common heart rhythm disorder where the heart beats irregularly and often rapidly. The study aims to compare two treatment methods to restore a normal heart rhythm, known as sinus rhythm, in patients who have recently developed AF. The treatments being compared are intravenous flecainide alone and a combination of intravenous flecainide with oral ranolazine. Flecainide and ranolazine are medications used to help control heart rhythm.
The purpose of the study is to determine which treatment is more effective in restoring normal heart rhythm in patients who have experienced AF for less than 48 hours. Participants in the study will receive either the combination of flecainide and ranolazine or flecainide alone. The study will monitor how quickly and effectively each treatment restores normal heart rhythm.
Participants will be observed to see how many of them return to a normal heart rhythm within three hours and six hours after starting the treatment. The study will help to understand if adding ranolazine to flecainide provides any additional benefit in treating recent onset AF compared to using flecainide alone. This information could be valuable in improving treatment strategies for patients with this heart condition.
