Early recognition, rapid institution of appropriate cardiac monitoring, and replacement therapy are essential. An endocrinal work-up may be necessary to exclude primary disorders of calcium metabolism. We report four cases documenting the varied clinical spectrum in which hypocalcaemic-induced prolongation of the QT interval and arrhythmia can occur in childhood.<\/jats:p>","DOI":"10.1017\/s1047951104006134","type":"journal-article","created":{"date-parts":[[2005,1,28]],"date-time":"2005-01-28T15:59:26Z","timestamp":1106927966000},"page":"667-670","source":"Crossref","is-referenced-by-count":14,"title":["Long on QT and low on calcium"],"prefix":"10.1017","volume":"14","author":[{"given":"Timothy J.","family":"Bradley","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel L.","family":"Metzger","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shubhayan","family":"Sanatani","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2005,1,21]]},"reference":[{"key":"S1047951104006134_ref009","doi-asserted-by":"crossref","unstructured":"Huang TC , Cecchin FC , Mahoney P , Portman MA .
