Abstract

Objective: The aim of this study was to determine the accuracy of trans-esophageal electrophysiological study (TEEPS) in the diagnosis and differentiation of mechanisms of supraventricular tachycardia in pediatric patients. Methods: A total of 132 patients who underwent TEEPS at our institution were included. Demographic features and symptoms of patients were evaluated and the patients were divided into three groups to compare the inducibility of tachycardia: Symptom group was consisting of 91 patients who had symptoms of arrhythmias, Wolf Parkinson White group was consisting of 18 patients who had Wolf Parkinson White pattern on surface electrocardiogram, and Tachycardia group was consisting of 23 patients who had previously detected or ongoing tachycardia on electrocardiographic monitoring. Results: Forty nine male (37.1%), and 83 female (62.9%) patients with an average age of 12.3 ± 3.1 years (range: 4.7-18) attended this study. Tachycardia was induced in a total of 40 procedures (40/132, 30.3%): 13/91 (14.3%) in Symptom group, 7/18 (38.9%) in WPW group and 20/23 (86.9%) in Tachycardia group. Conclusion: TEEPS is a safe and valuable diagnostic method to evaluate the patients with symptoms possibly related with arrhythmia or in the management of patients who have any arrhythmias.
