Additional Diagnostic Value of Very Prolonged Observation by Implantable Loop Recorder in Patients with Unexplained Syncope

Abstract

Prolonging observation up to 4 years increased the diagnostic value of ILR in syncopal patients and was safe. A quarter of patients diagnosed needed more than 18 months of follow-up. As consequence, when a strategy of prolonging monitoring is chosen, monitoring should be maintained even for several years until diagnosis is established.
