title: [Event recorder in cryptogenic stroke : Accepted and feasible indications].
abstract: It was proven in multiple studies that about 30 % of cryptogenic strokes are related to clinically silent atrial fibrillation (AF). There is an opportunity for prolonged ECG monitoring mainly through an implanted event recorder after completion of conventional diagnostic methods in an unidentified stroke source. The Crystal AF study has proven, together with other results, improved AF detection through prolonged monitoring for up to 36 months. An implanted event recorder for 2-3 years is suitable for this particular purpose. In addition, telemonitoring which is available in some recent models offers prompt detection and allows necessary therapies (e.g., oral anticoagulants) to be initiated. The implantation of an event recorder should also be considered in patients with a previous history of neurological symptoms in the context of undetectable sources of stroke or transient ischemic attack (TIA).
