Introduction: Close to 25% of cerebrovascular events are related to paroxistic atrial fibrillation (AF), that is why AF patients need to receive permanent oral anticoagulation. We need to identify them to prevent the events. The usual test employed has been the 24 hours Holter. Methods: In a period of 21.5 months, 100 patients with presumptive diagnosis of acute ischemic cerebrovascular event or transient ischemic attack of embolic origin, underwent 96 hours Holter monitoring to detect paroxysmal atrial fibrillation. Results: In nearly 7% of these patients this kind of arrhythmia was found, as well as, in 7.8% of those with confirmed stroke without evidence of cardioembolic source. Discusion: We conclude that the 96 hours Holter is better than the routinary 24-hour Holter, though, in order to incresae the sensitivity of this test, it is worthwhile to choose patientes with higher probability to present this arrhytmia.
