Ambulatory electrocardiographic monitoring: use of the implantable loop recorder in the evaluation of syncope.
Syncope may be related to a large spectrum of medical and psychologic disorders, yet the precise etiology is often difficult to determine. Although the evaluation of syncope involves extensive testing, nearly 50% of these individuals remain without definitive diagnosis. Because of the infrequent and unpredictable nature of syncope, many ambulatory screening techniques are not suited to diagnose syncope. The use of an implantable loop recording device provides continuous monitoring of heart rate and rhythm during syncopal events and may help clinicians arrive at a more precise diagnosis in a more timely manner. The Reveal Plus implantable loop recorder (ILR) (Medtronic USA, Minneapolis, Minn) has demonstrated its clinical utility in evaluating syncope and drug-refractory seizure disorders.
