Non-rheumatic atrial fibrillation is the most frequent etiology of cardioembolic cerebral infarction. It is often asymptomatic or slightly symptomatic, does not interfere with daily life and is unknown to the general population, which makes it difficult to discover, often during the stages of complications such as cerebral infarction, whereas at these stages the consequences are severe and often disabling throughout life. As for patients who have already suffered a cardioembolic stroke, the risk of recurrence is high if it is secondary to AF that is not detected. In daily practice in the Neurology Unit of the CHU Joseph Raseta Befelatanana, the search for FA after cerebral infarction is systematic although all the investigations necessary for screening are not always all carried out. Thus, the discovery and knowledge of the characteristics of these AFs at the origin of cerebral infarctions would make it possible to improve their secondary prevention.
