Furthermore, the association between obstructive sleep apnea (OSA) and bradyarrhythmias is well described. However, only a few cases of bradyarrhythmias observed during rapid eye movement (REM) sleep or REM sleep-related bradyarrhythmia syndrome, as it is known, have been documented in the literature.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Case Summary<\/jats:title>\n                  <jats:p>Here, we report another example of this syndrome. This was diagnosed during polysomnography in a middle-aged male and was independent of OSA. Several pauses, up to 5.7 seconds in duration, were observed during the study. A decision was made not to insert a pacemaker in this instance.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Discussion<\/jats:title>\n                  <jats:p>The mechanism behind such bradyarrhythmias is not well established. However, features of autonomic lability were observed on the patient\u2019s ECG monitoring during stress testing. Such autonomic lability with vagal predominance may be the driver of the bradyarrhythmias. It is unknown whether they represent a benign incidental finding or not due to limited case numbers. Furthermore, there is currently no clear consensus on their management. This stresses the need for further research to confirm their pathophysiological basis and develop clearer management strategies.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/ehjcr\/ytaf120","type":"journal-article","created":{"date-parts":[[2025,3,6]],"date-time":"2025-03-06T06:25:21Z","timestamp":1741242321000},"source":"Crossref","is-referenced-by-count":0,"title":["A Rare Case of Rapid Eye Movement Sleep-Related Bradyarrhythmia Syndrome with High-Grade AV Block, a case report"],"prefix":"10.1093","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-4684-9765","authenticated-orcid":false,"given":"William","family":"Griffin","sequence":"first","affiliation":[{"name":"Department of Respiratory Medicine, St. Vincent\u2019s University Hospital , Dublin ,","place":["Ireland"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-3185-1112","authenticated-orcid":false,"given":"Craig","family":"McDonnell","sequence":"additional","affiliation":[{"name":"Sleep Laboratory, St Vincent\u2019s Private Hospital , Dublin ,","place":["Ireland"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David","family":"Keane","sequence":"additional","affiliation":[{"name":"Department of Cardiology, St. Vincent\u2019s University Hospital , Dublin ,","place":["Ireland"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John","family":"Garvey","sequence":"additional","affiliation":[{"name":"Department of Respiratory Medicine, St. Vincent\u2019s University Hospital , Dublin ,","place":["Ireland"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2025,3,6]]},"container-title":["European Heart Journal - Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/academic.oup.com\/ehjcr\/advance-article-pdf\/doi\/10.1093\/ehjcr\/ytaf120\/62298292\/ytaf120.pdf","content-type":"application\/pdf","content-version":"am","intended-application":"syndication"},{"URL":"https:\/\/academic.oup.com\/ehjcr\/advance-article-pdf\/doi\/10.1093\/ehjcr\/ytaf120\/62298292\/ytaf120.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,3,6]],"date-time":"2025-03-06T06:25:21Z","timestamp":1741242321000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/ehjcr\/advance-article\/doi\/10.1093\/ehjcr\/ytaf120\/8056092"}},"subtitle":[],"editor":[{"given":"Felix","family":"Wiedmann","sequence":"additional","affiliation":[],"role":[{"role":"editor","vocabulary":"crossref"}]}],"short-title":[],"issued":{"date-parts":[[2025,3,6]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1093\/ehjcr\/ytaf120","relation":{},"ISSN":["2514-2119"],"issn-type":[{"type":"electronic","value":"2514-2119"}],"subject":[],"published":{"date-parts":[[2025,3,6]]},"article-number":"ytaf120"}}
