Median age at implantation 11.3 years (range 1.8\u201317.6); median follow-up period 15 months (range 2\u201358). The main presenting complaint was syncope in 26 (76.5%), seizures in 6 (17.6%) and palpitations in 2 (5.9%). After implantation, 19 (55.9%) patients had symptom recurrence. Of these, 11 were shown to have sinus rhythm during symptoms and 8 had an abnormal ECG. Four patients had asystole >3 seconds and were diagnosed with reflex asystolic syncope; 2 had polymorphic ventricular tachycardia. One patient who already had a diagnosis of long QT syndrome was shown to have ventricular ectopy during symptoms and \u03b2-blockers were increased. One patient had transient complete heart block during symptoms but refused a pacemaker. In almost half the patients (44.1%), symptoms resolved after implantation. Complications requiring removal of the device occurred in 6 (15.8%) implants.<\/jats:p>\n <\/jats:sec>\n \n Conclusions:<\/jats:title>\n In children with syncope and palpitations, the implantable loop recorder appears to be an excellent method of effecting a \u201ccure\u201d in almost 50% of subjects. For those who remain symptomatic, it is successful in determining cardiac rhythm during symptoms, but the complication rate in children may be higher than that of adults.<\/jats:p>\n <\/jats:sec>","DOI":"10.1136\/hrt.2007.121855","type":"journal-article","created":{"date-parts":[[2007,7,30]],"date-time":"2007-07-30T20:19:26Z","timestamp":1185826766000},"page":"888-891","source":"Crossref","is-referenced-by-count":18,"title":["The implantable loop recorder in children"],"prefix":"10.1136","volume":"94","author":[{"given":"B","family":"Yeung","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K","family":"McLeod","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2007,7,30]]},"reference":[{"key":"2025092100083648000_94.7.888.1","first-page":"286","article-title":"Analysis of 2017 Holter records in pediatric patients.","volume":"42","author":"Ayabakan","year":"2000","journal-title":"Turk J Pediatr"},{"key":"2025092100083648000_94.7.888.2","doi-asserted-by":"publisher","DOI":"10.1001\/archpedi.1990.02150260058028"},{"key":"2025092100083648000_94.7.888.3","doi-asserted-by":"publisher","DOI":"10.1542\/peds.113.2.248"},{"key":"2025092100083648000_94.7.888.4","doi-asserted-by":"publisher","DOI":"10.1053\/euhj.2000.2398"},{"key":"2025092100083648000_94.7.888.5","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.0000018125.31973.87"},{"key":"2025092100083648000_94.7.888.6","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.99.3.406"},{"key":"2025092100083648000_94.7.888.7","doi-asserted-by":"publisher","DOI":"10.1161\/hc3601.095708"},{"key":"2025092100083648000_94.7.888.8","doi-asserted-by":"publisher","DOI":"10.1542\/peds.112.3.e228"},{"key":"2025092100083648000_94.7.888.9","doi-asserted-by":"publisher","DOI":"10.1054\/jelc.2002.37170"},{"key":"2025092100083648000_94.7.888.10","first-page":"105","article-title":"Diagnostic Yield of the implantable loop recorder to detect the mechanism of syncope \u2013 a single center long term experience of a tertiary care center.","volume":"94","author":"Brunckhorst","year":"2005","journal-title":"Schweiz Rundsch Med Prax"},{"key":"2025092100083648000_94.7.888.11","doi-asserted-by":"publisher","DOI":"10.1016\/j.eupc.2004.09.003"},{"key":"2025092100083648000_94.7.888.12","doi-asserted-by":"publisher","DOI":"10.1046\/j.1460-9592.2000.01532.x"},{"key":"2025092100083648000_94.7.888.13","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2004.11.033"},{"key":"2025092100083648000_94.7.888.14","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.105.535161"},{"key":"2025092100083648000_94.7.888.15","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(01)01680-1"},{"key":"2025092100083648000_94.7.888.16","unstructured":"Brignole M Alboni P Benditt DG .
