Time to manual activation of implantable loop recorders--implications for programming recording period: a 10-year single-centre experience.

Aim: A new generation of commercially available implantable loop recorders (ILRs) has improved arrhythmia detection algorithms but reduced manually activated ECG storage duration. We investigated the effect that this would have had on symptom-arrhythmia correlation in a retrospective patient cohort.

Method And Results: Retrospective review of all patients receiving a Medtronic Reveal 9525/9526 for the investigation of unexplained syncope or pre-syncope in our centre between 1998 and 2008.
