Unexplained Syncope: Can We Predict the Outcome of Prolonged Monitoring with the Implantable Loop Recorder?
Syncope is a complex clinical symptom with multiple etiologies that are often difficult to discern. The major obstacles to diagnosis are the unpredictable and infrequent nature of events and the high spontaneous remission rate [1, 2]. Clinicians rely on clinical assessment and abnormal laboratory results to make a diagnosis by inference in many cases. Advances in long term cardiac monitoring techniques with the implantable loop recorders have added a powerful tool in the field for arrhythmia detection [3–9]. Optimal deployment of this technology is aimed to enhance diagnostic yield while directing scarce resources at patients with a high likelihood of device utilization [5,10–12].
