Recurrent seizure diagnosed by the insertable loop recorder

Abstract

Introduction: The Insertable Loop Recorder (ILR) has emerged as an important new tool in the diagnostic armamentarium for patients with syncope.

Methods and results: A case report illustrates how the ILR unexpectedly led to the diagnosis of seizure as the explanation for a man's recurrent, but infrequent episodes of sudden loss of consciousness.

Conclusions: This case raises the possibility that the development of implantable recording devices which monitor physiologic parameters other than cardiac rhythm (eg. brain, nerve or muscle activity) may provide the long-term monitoring capability needed to improve the diagnostic yield for conditions, such as seizures, which occur infrequently.
