Importance of implantable loop recorder in patients with unexplaided syncope


Authors: R. Krausová
Published in the journal: Kardiol Rev Int Med 2007, 9(3): 177-181

Summary

Conventional tests have known limitations in the diagnosis of syncope. Implantable loop recorder (ILR) is capable to monitor continuously ECG over a period of several months with an option to record signals during a period of symptoms after post hoc telemetric activation. ILR is a useful diagnostic tool in syncopal patients with infrequent symptoms and negative results of previous conventional tests.

Keywords:
long-term ECG monitoring, unexplained syncope, implantable loop recorder, bradyarrhythmia, tachyarrhythmia
