Dronedarone Rhythm Intervention for Early Atrial Fibrillation

The purpose of this study is to compare two commonly used types of medicine for treating atrial fibrillation (also called AF), a condition that causes an irregular heart rhythm. This study is for adults who have been diagnosed with AF within the past year. Researchers want to find out which medicine is more effective, safer, and provides a better quality of life for patients needing to control their heart rhythm. Participants who agree to join the study will be randomly assigned (like flipping a coin) to one of two groups: Group 1: Will receive the medicine Dronedarone. Group 2: Will receive a standard medicine from the 'Class Ic' group (such as flecainide or propafenone). The study will follow participants for at least 12 months. Researchers will compare how well each medicine works to prevent AF from coming back. They will also carefully track any side effects and changes in participants' quality of life during the study.
