Abstract
Background: QT dispersion (QTd) especially after ischemic heart
disease and myocardial infarction is a prognostic predictor of mortality,
in adult medicine.
Objective: This study was undertaken to determine the correlation
between QT dispersion and neonatal stress. Neonates were divided
into 3 groups: normal term (30 cases), normal preterm (30 cases) and
sick neonates (36 cases), born between October 2001 and June 2002
in Hafez and Nemazee Hospitals affiliated to Shiraz University of
Medical Sciences. Electrocardiogram (12 leads) was obtained and
QTd was calculated.
Result: QT dispersion in sick neonates was significantly higher than
normal neonates. The mean QTds in normal term group were 52.4±
24.47 ms in normal preterm, 69.3 ± 17.94ms and 100.8 ± 29.01ms in
sick neonates. In sick neonates, QTd correlated with the incidence
rate of mortality.
