Comparative Evaluation of Corrected QT and Ionized Calcium in Children.

Convulsion is one of the most common problems in children and hypocalcemia is one the most frequent etiological items in children's convulsion. Corrected QT (QTc) in EKG is prolonged in hypocalcemia, so it can be a useful tool for evaluation of serum ionized calcium. In three groups (first seizure, multiple seizures, without seizure or control ) every 25 cases, QTc, serum ionized ca, total ca, ABG, and serum albumin level have been checked in the Department of Pediatrics of Imam Khomeini Hospital and outpatient department of Ahari children's medical center in 2008.
