Key result
ILR monitoring identifies the responsible mechanism in 53% of recurrent syncope or pre-syncope cases.
Why the study?
In about 30% of patients with syncope, the responsible mechanisms remain unrecognised and arrhythmic aetiology is difficult to rule out.
Does implantable loop recorder monitoring improve the diagnosis of unexplained syncope in patients with negative traditional work-up?
Population
34 subjects with at least two unexplained syncopal episodes and negative neurological and cardiovascular work-up
Comparison
Implantable loop recorder (Reveal Plus) monitoring
Design
Observational cohort study

Does implantable loop recorder monitoring improve the diagnosis of unexplained syncope in patients with negative traditional work-up?
Implantable loop recorder monitoring facilitates the identification of underlying arrhythmic mechanisms in patients with unexplained syncope, effectively guiding therapeutic management.
Lombardi et al. (2005) conducted an observational in Unexplained syncope (n=34). Implantable loop recorder (Reveal Plus) was evaluated on Identification of mechanisms responsible for recurrences (syncope or pre-syncope). Implantable loop recorder monitoring successfully identified the responsible mechanism in 53% of the total cohort who experienced recurrent syncope or pre-syncope.
