Hypocalcaemia mimicking long QT syndrome: case report

Eur J Pediatr. 2008 Feb;167(2):233-5. doi: 10.1007/s00431-007-0438-7. Epub 2007 May 8.


We describe a teenage girl who presented with syncope on exertion and prolonged QT on electrocardiogram (ECG). She was found to be hypocalcaemic due to hypoparathyroidism. Following oral calcium and vitamin D supplementation, there were no further episodes of syncope with normalization of the QT segment. This case highlights the need to consider all causes of a long QT segment.
