Usefulness of implantable loop recorders in office-based practice for evaluation of syncope in patients with and without structural heart disease

Early use of an implantable loop recorder for evaluating unexplained syncope in an office-based electrophysiology practice is an effective approach in patients with and without structural heart disease. Documentation of rhythm with an implantable loop recorder at the time of symptoms is possible in approximately 50% and 80% of patients in both groups after 1 and 2 years of follow-up, respectively.
