INTRODUCTION: The aim of this study was to evaluate the inducibility of tachycardia by transesophageal electrophysiologic study (TEEPS) in patients with documented supraventricular tachycardia (SVT) on electrocardiography and to investigate the accuracy of TEEPS records by comparing with intracardiac electrophysiologic study (IEPS).
MATERIAL AND METHODS: The TEEPS records of patients having documented electrocardiography during SVT were reviewed. The results of TEEPS in 43 of 85 patients were compared with results of IEPS for compatibility of diagnosis.
RESULTS: A total 85 patients, 46 male and 39 female, mean weight 35.1 kg (36-87), aged 1 month-17 years, were included. Tachycardia was induced by TEEPS in 79 of 85 patients with documented electrocardiography (sensitivity 92.9%). IEPS for diagnosis or ablation was conducted in 40 patients having inducible tachycardia and three of six who had no inducible tachycardia by TEEPS. Tachycardia was induced by IEPS in 39 of 40 (97.5%) patients who had inducible tachycardia and two of three who had no inducible tachycardia by TEEPS. Mechanisms of tachycardias were similar in 97.5% of patients (37/39) who had inducible tachycardia in TEEPS and IEPS. One of the patients with atrioventricular reentry tachycardia by TEEPS was diagnosed as atrioventricular nodal reentry tachycardia (AVNRT) and the other one was diagnosed as atypical AVNRT and atrial tachycardia by IEPS.
CONCLUSION: The rates of inducibility and mechanisms of tachycardias by TEEPS in children having documented SVT were similar with those obtained from IEPS.
