QT Interval Changes in Children With Febrile Convulsion Compared With Healthy

Introduction: Febrile seizure is a temperature-related seizure that affects the QT interval. The purpose of this study was to evaluate the changes in the QT interval caused by febrile convulsion (FC) compared with healthy children. Methods: This case-control study examined 180 children equally distributed between patients and controls. The study was conducted at the Ali Ebne Abi Talib Hospital in Zahedan City, Iran. The disease was diagnosed and confirmed based on standard definitions of FC. QT interval was measured by ECG and interpreted by a pediatric cardiologist, and collected data were analyzed using SPSS software, version 19 with a 0.05 significant level. Results: =52.674, P<0.001) and the other QT parameters were the same in FC children with different age groups (P>0.05). Conclusion: It is concluded that dispersion corrected QT, corrected QT, and dispersion QT changed significantly in children with FC in comparison with the healthy children with constant values in children with FC in different age groups. Highlights: Corrected QT, dispersion QT and corrected-dispersion QT changed in children with febrile convulsion.Among the children with abnormal dispersion QT, febrile convulsion were not seen more when children with febrile convulsion (FC) were more in abnormality levels of QTc and QTcd. Plain Language Summary: The study aimed to evaluate changes in electrocardiography parameters in children with febrile convulsion and found positive correlation.
