EVALUATING QT DISPERSION IN CHILDREN WITH SYNCOPE ATTACKS BASED ON BLOOD CRITERIA

Abstract

Introduction: The aim of this study was to evaluate the QT dispersion in childrenwith syncope.

Methodology: This was a case control study performed on 50 children withsyncope attacks (case group) referred to the Clinic of Shahid Beheshti Hospital inKashan during 2014 and healthy children (control group) referred to the center forcauses such as a cold or developmental examination. After explaining the projectto the parents, data was obtained from the case and control group. Then; usingChi-square, Mann-Whitney, Kolmogorov–Smirnov, Levene's, Kruskal-Wallstatistical tests, the data was analyzed.

Results: Total of, 100 children took part in the study, the participants were dividedinto two groups of case (n=50) and control (n=50).Among the studied children,a total of 46 of them (46%) were boys and the rest were girls. The mean ageranges of children in the case and control groups (absence of syncope attacks)were 7.73± 2.33 and 8.09± 2.31 years, respectively (p=0.440).There was asignificant difference between them in terms of each of the 4 parameters(p<0.001), and the value of indices in the control group was significantly lessthan that of the patient group.

Conclusion: According to the results of the study, precise ECG examinating inchildren suspected of syncope attacks can be helpful in confirming the incidenceof syncope.
