Syncope of Unknown Origin After Electrophysiologic Study and Head-Up Tilt Test: How Useful is an Implantable Loop Recorder?

Conference paper


Syncope is a frequent disorder that can be due to very different etiologies. The etiologic diagnosis of syncope is a complex task. In most of the series in the literature, in 40%–60% [1, 2] of patients the etiology of syncope remains unknown. In most patients, the anamnesis, physical examination and baseline ECG are the most helpful tools in diagnosing the etiology of syncope [1]. In patients in whom the etiology of syncope remains unknown after the initial clinical evaluation, many different additional tests can be performed.
