After cardiopulmonary resuscitation, return of spontaneous circulation was achieved 30\u2005min later. Her post-resuscitation ECG showed a prolonged QT interval which progressively normalised over the same day. Her laboratory investigations revealed hypocalcaemia while other electrolytes were within normal limits. A diagnosis of ventricular arrhythmia secondary to structural heart disease further precipitated by hypocalcaemia was made. Further hospital stay did not reveal a recurrence of prolonged QT interval or other arrhythmias except for an episode of non-sustained ventricular tachycardia. However, the patient suffered diffuse hypoxic brain encephalopathy secondary to prolonged cardiopulmonary resuscitation.<\/jats:p>","DOI":"10.1136\/bcr-2014-205055","type":"journal-article","created":{"date-parts":[[2014,5,14]],"date-time":"2014-05-14T14:49:45Z","timestamp":1400078985000},"page":"bcr2014205055","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":3,"title":["Mitral valve prolapse and electrolyte abnormality: a dangerous combination for ventricular arrhythmias"],"prefix":"10.1136","volume":"2014","author":[{"given":"Ali Raza","family":"Rajani","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vagishwari","family":"Murugesan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fahad Omar","family":"Baslaib","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Muhammad Anwer","family":"Rafiq","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2014,5,14]]},"reference":[{"key":"2025042703390068000_2014.may14_1.bcr2014205055.1","doi-asserted-by":"publisher","DOI":"10.1146\/annurev-med-022811-091602"},{"key":"2025042703390068000_2014.may14_1.bcr2014205055.2","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.108.190748"},{"key":"2025042703390068000_2014.may14_1.bcr2014205055.3","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(05)17869-6"},{"key":"2025042703390068000_2014.may14_1.bcr2014205055.4","doi-asserted-by":"publisher","DOI":"10.1016\/0167-5273(90)90244-Y"},{"key":"2025042703390068000_2014.may14_1.bcr2014205055.5","doi-asserted-by":"publisher","DOI":"10.1017\/S1047951100012920"},{"key":"2025042703390068000_2014.may14_1.bcr2014205055.6","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8159.1994.tb01466.x"},{"key":"2025042703390068000_2014.may14_1.bcr2014205055.7","first-page":"1306","article-title":"[Sudden cardiac arrest in ventricular fibrillation mechanism as a first manifestation of primary mitral valve prolapse]","volume":"69","author":"Brzyzkiewicz","year":"2012","journal-title":"Przegl Lek"},{"key":"2025042703390068000_2014.may14_1.bcr2014205055.8","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2013.02.060"},{"key":"2025042703390068000_2014.may14_1.bcr2014205055.9","doi-asserted-by":"publisher","DOI":"10.1007\/s10554-009-9514-6"},{"key":"2025042703390068000_2014.may14_1.bcr2014205055.10","first-page":"125","article-title":"[Electrolyte abnormalities and ventricular arrhythmias in children with mitral valve prolapse]","volume":"11","author":"Bobkowski","year":"2001","journal-title":"Pol Merkur Lekarski"},{"key":"2025042703390068000_2014.may14_1.bcr2014205055.11","first-page":"220","article-title":"[Influence of autonomic nervous system on electrolyte abnormalities in children with mitral valve prolapse]","volume":"14","author":"Bobkowski","year":"2003","journal-title":"Pol Merkur Lekarski"},{"key":"2025042703390068000_2014.may14_1.bcr2014205055.12","first-page":"35","article-title":"The importance of magnesium status in the pathophysiology of mitral valve prolapse","volume":"18","author":"Bobkowski","year":"2005","journal-title":"Magnes Res"},{"key":"2025042703390068000_2014.may14_1.bcr2014205055.13","doi-asserted-by":"publisher","DOI":"10.1111\/j.1542-474X.2005.00630.x"},{"key":"2025042703390068000_2014.may14_1.bcr2014205055.14","doi-asserted-by":"publisher","DOI":"10.1053\/eupc.2001.0186"},{"key":"2025042703390068000_2014.may14_1.bcr2014205055.15","doi-asserted-by":"publisher","DOI":"10.1136\/hrt.74.1.96-a"},{"key":"2025042703390068000_2014.may14_1.bcr2014205055.16","doi-asserted-by":"publisher","DOI":"10.1007\/s00246-007-9095-x"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2014-205055","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,27]],"date-time":"2025-04-27T10:39:08Z","timestamp":1745750348000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2014-205055"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,5,14]]},"references-count":16,"alternative-id":["10.1136\/bcr-2014-205055"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2014-205055","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2014,5,14]]}}}
