Implantable Loop Recorder Allows an Etiologic Diagnosis in One-Third of Patients

Implantable loop recorders in patients with unexplained syncope: Clinical predictors of pacemaker implantation

“…This proportion is comparable to previous published data (14-21%) [9,15]. The overall diagnosis rate was higher than reported by others (43.4%), whereas data from large registries reveal a final diagnosis in approximately 30% of the patients [9,12,13,15].…”

Differences in the yield of the implantable loop recorder between secondary and tertiary centers

“…This is a sub-study of the Reveal Spanish Registry [7], which was designed as a prospective, observational and multicenter study on a national level. All centers where ILR devices are inserted were invited to take part.…”

2018 ESC Guidelines for the diagnosis and management of syncope

“…I C ILR is indicated in an early phase of evaluation in patients with recurrent syncope of uncertain origin, absence of high-risk criteria (listed in Table 6), and a high likelihood of recurrence within the battery life of the device. 175,176,[181][182][183][184]202 , Table 5 I A ILR is indicated in high-risk (criteria listed in Table 6) patients in whom a comprehensive evaluation did not demonstrate a cause of syncope or lead to a specific treatment, and who do not have conventional indications for primary prevention ICD or pacemaker indication. 174,180,187,188,195 , Supplementary Data Tables 5 and 6 I A Arrhythmic syncope is confirmed when a correlation between syncope and an arrhythmia (bradyarrhythmia or tachyarrhythmia) is detected.…”
