Although generally considered safe under specific protocols, electromagnetic interference may still lead to clinically misleading recordings.<\/jats:p>\n <\/jats:sec>\n \n Case summary<\/jats:title>\n A 76-year-old woman with a history of mitral valve replacement and paroxysmal atrial fibrillation underwent implantation of an implantable cardiac monitor (Abbott Confirm Rx) for the evaluation of recurrent presyncope. During a brain MRI at another hospital (1.5-T GE SIGNA Creator), the device captured high-amplitude polymorphic signals resembling torsade de pointes, whereas a 12-lead electrocardiogram obtained shortly after MRI confirmed sinus rhythm with a normal QT interval. A repeat MRI at our institution using a 3.0-T Siemens MAGNETOM Lumina scanner with the same time-of-flight magnetic resonance angiography sequence did not reproduce the artefact. Phantom testing on the outside hospital\u2019s scanner also failed to demonstrate the phenomenon. However, the artefact was reproducibly observed during a follow-up MRI performed 6 months later using the same scanner. No similar findings were observed in other patients with implantable cardiac monitors scanned using the same system.<\/jats:p>\n <\/jats:sec>\n \n Discussion<\/jats:title>\n MRI-related artefacts in implantable loop recorders have been previously reported. The present case demonstrates a reproducible torsade de pointes-like morphology specifically associated with the pre-scan phase on a particular MRI system, suggesting a device\u2013scanner\u2013patient interaction rather than true arrhythmia.<\/jats:p>\n <\/jats:sec>","DOI":"10.1093\/ehjcr\/ytag360","type":"journal-article","created":{"date-parts":[[2026,5,12]],"date-time":"2026-05-12T11:38:33Z","timestamp":1778585913000},"source":"Crossref","is-referenced-by-count":0,"title":["Magnetic resonance imaging-induced artefact mimicking torsade de pointes in a patient with an implantable cardiac monitor: a case report"],"prefix":"10.1093","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6381-2247","authenticated-orcid":false,"given":"Yasuyuki","family":"Toyama","sequence":"first","affiliation":[{"name":"Department of Cardiovascular Medicine, Iseikai International General Hospital , 4-14 Minamiogi-machi, Kita-ku, Osaka 530-0052 ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yusuke","family":"Taniguchi","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Medicine, Iseikai International General Hospital , 4-14 Minamiogi-machi, Kita-ku, Osaka 530-0052 ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mayu","family":"Morisue","sequence":"additional","affiliation":[{"name":"Department of Clinical Engineering, Iseikai International General Hospital , 4-14 Minamiogi-machi, Kita-ku, Osaka 530-0052 ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshiaki","family":"Matsuo","sequence":"additional","affiliation":[{"name":"Department of Clinical Engineering, Iseikai International General Hospital , 4-14 Minamiogi-machi, Kita-ku, Osaka 530-0052 ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2026,5,13]]},"reference":[{"key":"2026052613215293900_ytag360-B1","doi-asserted-by":"crossref","first-page":"419","DOI":"10.1161\/CIRCEP.113.000116","article-title":"Magnetic resonance imaging and implantable devices","volume":"6","author":"Nazarian","year":"2013","journal-title":"Circ Arrhythm Electrophysiol"},{"key":"2026052613215293900_ytag360-B2","doi-asserted-by":"crossref","first-page":"755","DOI":"10.1056\/NEJMoa1603265","article-title":"Assessing the risks associated with MRI in patients with a pacemaker or defibrillator","volume":"376","author":"Russo","year":"2017","journal-title":"N Engl J Med"},{"key":"2026052613215293900_ytag360-B3","doi-asserted-by":"crossref","first-page":"501","DOI":"10.1002\/jmri.24011","article-title":"ACR guidance document on MR safe practices: 2013","volume":"37","author":"Expert Panel on MR Safety","year":"2013","journal-title":"J Magn Reson Imaging"},{"key":"2026052613215293900_ytag360-B4","doi-asserted-by":"crossref","first-page":"e97","DOI":"10.1016\/j.hrthm.2017.04.025","article-title":"2017 HRS expert consensus statement on magnetic resonance imaging and radiation exposure in patients with cardiovascular implantable electronic devices","volume":"14","author":"Indik","year":"2017","journal-title":"Heart Rhythm"},{"key":"2026052613215293900_ytag360-B5","doi-asserted-by":"crossref","first-page":"2799","DOI":"10.1161\/CIRCULATIONAHA.113.005697","article-title":"Effects of external electrical and magnetic fields on pacemakers and defibrillators: from engineering principles to clinical practice","volume":"128","author":"Beinart","year":"2013","journal-title":"Circulation"},{"key":"2026052613215293900_ytag360-B6","first-page":"1367","article-title":"Outcome of patients with implantable loop recorders undergoing magnetic resonance imaging","volume":"91","author":"Gimbel","year":"2003","journal-title":"Am J Cardiol"},{"key":"2026052613215293900_ytag360-B7","doi-asserted-by":"crossref","first-page":"270","DOI":"10.1111\/j.1540-8159.2005.09520.x","article-title":"Safe performance of magnetic resonance imaging on patients with implantable loop recorders","volume":"28","author":"Gimbel","year":"2005","journal-title":"Pacing Clin Electrophysiol"}],"container-title":["European Heart Journal -
