Recent studies have shown that the incidence of syncope in emergency departments is 0.9–1.7% of all attendances. One-third of these patients are diagnosed with unexplained syncope despite complete medical check-up, and several non-invasive and invasive examinations. An implantable loop recorder (ILR) has a loop memory, which continuously records the electrical activity of the heart (Figure 1). When the ILR is activated by a patient with symptoms of syncope, the electrical activity of the heart several minutes before activation is stored and can be retrieved for analysis. ILR is a promising technology for elucidating the cause of syncope in patients with unexplained syncope.
