The cause of the hyponatraemia was beer potomania. The co-occurrence of reversible first, second and third-degree heart blocks and hyponatraemia has been described in a few published case reports. However, this case is noteworthy as the AV block persisted, despite correction of serum sodium concentration as opposed to other published cases, which meant that the patient required a permanent pacemaker.<\/jats:p>","DOI":"10.1136\/bcr-2018-224260","type":"journal-article","created":{"date-parts":[[2018,3,14]],"date-time":"2018-03-14T08:20:22Z","timestamp":1521015622000},"page":"bcr-2018-224260","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":3,"title":["Beer, hyponatraemia and cardiac conduction defects"],"prefix":"10.1136","volume":"2018","author":[{"given":"Simon","family":"Mifsud","sequence":"first","affiliation":[{"name":"Department of Medicine, Mater Dei Hospital, Msida, Malta"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Emma Louise","family":"Schembri","sequence":"additional","affiliation":[{"name":"Department of Medicine, Mater Dei Hospital, Msida, Malta"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthew","family":"Mercieca Balbi","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Mater Dei Hospital, Msida, Malta"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mark","family":"Gruppetta","sequence":"additional","affiliation":[{"name":"Department of Diabetes and Endocrinology, Mater Dei Hospital, Msida, Malta"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James","family":"Clark","sequence":"additional","affiliation":[{"name":"Department of Medicine, Mater Dei Hospital, Msida, Malta"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2018,3,14]]},"reference":[{"key":"2025082800361141000_2018.mar14_1.bcr-2018-224260.1","doi-asserted-by":"publisher","DOI":"10.1016\/j.semnephrol.2009.03.004"},{"key":"2025082800361141000_2018.mar14_1.bcr-2018-224260.2","first-page":"233","article-title":"Electrolyte disorders and arrhythmogenesis","volume":"18","author":"El-Sherif","year":"2011","journal-title":"Cardiol J"},{"key":"2025082800361141000_2018.mar14_1.bcr-2018-224260.3","doi-asserted-by":"crossref","first-page":"165","DOI":"10.1002\/clc.4960140214","article-title":"Cardiac conduction defects associated with hyponatremia","volume":"14","author":"Mouallem","year":"1991","journal-title":"Clin Cardiol"},{"key":"2025082800361141000_2018.mar14_1.bcr-2018-224260.4","doi-asserted-by":"crossref","unstructured":"Bhattarai N , Kafle P , Panda M .
