QT Interval Changes in Children With Febrile Convulsion Comparing With Healthy

A temperature-related seizure is a febrile seizure that affects the QT interval. The purpose of this study was to evaluate the changes in the QT interval caused by febrile convulsion compared with healthy children. Method This case-control study considered the distribution of 180 children equally shared between patients and controls. The study was conducted at the "Ali Ebne Abi Talib" Hospital in Zahedan, Iran. The disease diagnosed and confirmed based on standard definitions of febrile convulsion. QT interval measured by ECG and interpreted by a pediatric cardiologist and collected data were analyzed with SPSS 19 considering 0.05 as significant error. Results Among the ECG parameters, HR, R in aVL, S in V3, LVM, QTd, QTc and QTcd were significantly different in children with febrile convulsion compared to the peers. From those who had abnormal QTd, FC children were more frequented but not significant (CHI SQUARE=1.053, p=0.248), when children with FC were more in abnormality regarding QTc (CHI SQUARE=13.032, p24 months (p>0.05). LVM had the highest value in the age group of >24 months significantly (CHI SQUARE= 52.674, P0.05). Conclusion From the study concluded that dispersion corrected QT, corrected QT and dispersion QT changed significantly in children with febrile convulsion in comparing with the healthy children but with constant values in children with FC in different age groups.
