She also had congestive cardiac failure that responded to magnesium replacement. The mild hypomagnesaemia found in this patient was responsible for the refractory hypocalcaemia. Minor deficiencies of magnesium may cause severe hypocalcaemia and hypokalaemia that are refractory to replacement treatment. Prompt replacement of magnesium may prevent prolonged tetany, cardiac arrhythmias, and heart failure.<\/jats:p>","DOI":"10.1136\/bmj.291.6510.1680","type":"journal-article","created":{"date-parts":[[2009,4,2]],"date-time":"2009-04-02T11:00:59Z","timestamp":1238670059000},"page":"1680-1682","source":"Crossref","is-referenced-by-count":39,"title":["Electrolyte disturbances and cardiac failure with hypomagnesaemia in anorexia nervosa."],"prefix":"10.1136","volume":"291","author":[{"given":"V","family":"Fonseca","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C W","family":"Havard","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[1985,12,14]]},"reference":[{"key":"ref_1","first-page":"60","article-title":"Fluid and electrolyte disorders: magnesium","volume":"32","author":"DP, I.Brenton; TE, Gordon","year":"1984","unstructured":"I Brenton DP, Gordon TE.
