Popis: Introduction If the management of atrial fibrillation in its thromboembolic component knows more adherences to recommendations, it should be noted that the rhythmic component is experiencing a trend towards acceptance of the AF at the expense of a restoration strategy sinus rhythm. Purpose To evaluate the effectiveness of the drug cardioversion or electrical cardioversion in patients hospitalized in the cardiology department of HMIMV Rabat. Materials and Methods This is a prospective study conducted over a period of one year, including 45 patients with non-valvular AF, candidates for chemical or electrical cardioversion. All our patients have undergone transthoracic echocardiography, sometimes supplemented with a transesophageal echocardiography and an assessment of thyroid Results The average age of our patients was 52.7 years with a sex ratio 2/1. 25% of our patients had hypertensive heart disease, 8% ischemic heart disease, 4% dilated cardiomyopathy and the rest had a healthy heart. The average diameter of the left atrium was 41 cm with an average surface to 19 cm 2 . 60% of our patients have undergone cardioversion by external shock, and 40% of theme by injection of amiodarone or flecainide. The rate of restoration of sinus rhythm was 78%, with a recurrence rate at one month 19%. The predictive factors of recurrence were an ancient atrial fibrillation, a large left atrium and a score CHA2DS2-VASC ≥ 1. Conclusion This study, showing an acceptable level of restoration and maintenance of sinus rhythm, confirms the interest of promoting a strategy of rhythm control, subject to patient selection on predictors of success.
