The role of the implantable loop recorder in the investigation of recurrent syncope.

Recurrent syncope is a common clinical problem. Patients with recurrent syncope frequently undergo extensive investigations that consume significant health care resources. Nevertheless, in a large percentage of patients syncope remains unexplained. The implantable loop recorder is a recognized diagnostic tool that can provide a definitive diagnosis and thus permit specific treatment. We present the case of a woman with recurrent syncope who was referred to our cardiology department for further investigation. Her last episode had led to a fall that caused her serious injuries. The initial routine workup was negative for cardiac, neurologic or metabolic causes of syncope. The implantable loop recorder revealed an arrhythmic origin for the recurrent syncope. The patient was managed appropriately with pacemaker implantation and has remained asymptomatic for one year.
