Approximately half of OSAHS patients evidence severe cardiac rhythm disturbances, which are significantly reduced by CPAP. Holter recordings seem unable to precisely describe the incidence of severe brady-arrhythmias and the effect of treatment.

Undoubtedly this device is the current gold standard for the diagnosis of unexplained syncope. In the population we studied though, the device faced undersensing problems. Consequently, the device should be equipped with more advanced software for QRS morphology recognition, to improve the diagnostic accuracy of the recorder.
