Objective: It was aimed to analyze the etiological, laboratory and electrocardiographic aspects of pediatric patients who applied to our outpatient clinic with the complaint of syncope, and to determine the correct approach to these patients.

Material and Method: Epidemiological, etiological and laboratory data of patients who applied with the complaint of syncope between August 2020 and July 2021 were analyzed retrospectively. Electrocardiographic data of the patients were compared with the healthy control group.

Results: Fifty patients and 41 healthy control group were included in the study. It was observed that 22 (44.00%) of the patients presented with the first syncope, in 35 (70.00%) the syncope duration was less than 2 minutes and the median number of syncope was 2 (1-20). Prolonged standing was the most common trigger for syncope. The most common accompanying finding was pallor. Etiologically, vasovagal syncope (64.15%), orthostatic hypotension (15.09%) and psychogenic causes (15.09%) were found most commonly. Long QT syndrome was diagnosed in one patient and epilepsy was diagnosed in two patients. There was no significant difference between the patient and control groups in terms of PR, PRd, QT, QTd, QTc, QTcd, TPe, TPe/QTc, Pax, Taks, QRSax, QRS-T angle measurements.

Conclusion: In patients with syncope, the diagnosis can be made to a great extent with a well-received anamnesis, physical examination and electrocardiographic examination. The contribution of other examinations to the diagnosis is low. Parameters that are predictive of malignant arrhythmias, especially repolarization anomalies, on electrocardiographic do not differ from healthy patients.
