These clinical conditions can be determined by the evaluation of cardiac nodal functions with transesophageal electrophysiologic studies (TEEPS) 11,12 . There is no study that evaluated cardiac nodal function in pediatric cases suffering from vasovagal syncope.…”

“…In a study by Samson et al [23], tachycardia mechanisms identified by both TEEPS and IEPS in a pediatric population were compatible in 56 out of 57 patients. In another study by Erdogan et al [11] on 76 patients who underwent TEEPS prior to radio frequency ablation, the reported positive predictive value for TEEPS in correctly distinguishing SVT mechanism was 91 %. Volkmann et al [26] compared TEEPS and IEPS findings of 219 patients in a study where they observed that the exact electrophysiologic (4) AVNRT (3) AT (2), AVRT (1) Pediatr Cardiol mechanism of a tachycardia could not be ascertained by either procedure in 11 patients, whereas a discrepancy between the results of both procedures was reported in 9 patients.…”

“…Varying stimulus techniques are used in an attempt to trigger a tachyarrhythmia. TEEPS has been used in the differential diagnosis of SVTs such as AVRT, AVNRT, and atrial flutter, as well as for their termination, while also proving useful for the decision of medical treatment, the follow-up evaluation, and the indications for ablation [8,10,15,17,18,22,24].…”

In this study, we aimed to compare the results of transesophageal electrophysiologic studies (TEEPS) and intracardiac electrophysiologic studies (IEPS) in a cohort of pediatric patients with SVTs. The medical records of children aged between 0 and 18 years who underwent TEEPS between January 2007 and June 2012 were systematically reviewed, and those without pre-excitation and who underwent subsequent IEPS were identified. Post-procedural diagnoses were compared for compatibility. A total of 162 patients were included in the study with a mean age at diagnosis 11.6 ± 3.6 years. Tachycardia was induced in 152 patients by TEEPS and in 154 patients by IEPS. Overall, in 147 patients, tachycardia was induced by both TEEPS and IEPS. Diagnoses were compatible in 135 out of 147 patients (91.8 %). Nine out of the 12 patients with discrepant results were diagnosed with atrioventricular-reentrant tachycardia (AVRT) and three with atrioventricular nodal reentrant tachycardia (AVNRT) after TEEPS. Following IEPS, TEEPS diagnosis of AVRT was revised to typical AVNRT in 5 patients and atypical AVNRT in 4 patients. Two of the 3 patients who were diagnosed as having AVNRT following TEEPS were confirmed to have atrial tachycardia after IEPS, while the other patient was diagnosed with AVRT. Tachycardia terminated spontaneously in 3 patients, while overdrive pacing was attempted to terminate the tachycardia in 149 patients, with a success rate of 93.2 % (139/149). The diagnostic compatibility between TEEPS and IEPS is quite high. A diagnostic discrepancy mostly occurs in patients diagnosed with AVRT by TEEPS, and the possibility of atypical AVNRT should be considered in patients with a VA ≥70 ms to avoid such discrepancies.

“…Assessment of recurrence after successful ablation is usually performed using noninvasive methods such as clinical evaluation, exercise testing, or Holter monitoring (11). However, although these methods are the first step to assess the recurrence of tachycardia in practice, they are not always effective in children to assess the recurrence of tachycardia.…”

“…In our hospital protocol, TEEPS has been suggested for all patients who underwent successful RFA to check them approximately 3 months later in terms of recurrence, regardless of symptomatology because of our previous experience (11). We performed clinical evaluation, 24 h Holter monitoring, or exercise testing, and TEEPS in a routine evaluation of recurrence.…”

Objective:The aim of this study was to evaluate the efficacy of transesophageal electrophysiologic study (TEEPS) for the determination of supraventricular tachycardia (SVT) recurrences in symptomatic and asymptomatic children after successful radiofrequency ablation (RFA) for SVT.Methods:A total of 66 patients who underwent TEEPS after successful RFA were included. The demographic features, symptoms of the patients, and the characteristics of the recurrences induced by TEEPS were evaluated. The arrhythmia types induced during RFA were compared with those induced by TEEPS in terms of the compatibility of the diagnosis.Results:Forty-two (63.6%) girls and 24 (36.4%) boys with a mean age of 11.8±3.4 years were followed-up for 44.1±15.7 months. The average time between RFA and TEEPS was 5.2±5.9 months. The diagnoses during RFA were atrioventricular nodal reentrant tachycardia (AVNRT) in 47 of 66 patients, atrioventricular reentrant tachycardia (AVRT) in 18 of 66 patients, and ectopic atrial tachycardia in 1 of 66 patients. SVT was induced by TEEPS in 2 of 25 symptomatic and 5 of 41 asymptomatic patients. The SVT inducibility rate was 5.5% (1/18) and 12.7% (6/47) in patients with AVRT and AVNRT, respectively. In addition, 85.7% (6/7) of all recurrences occurred within 3.5 months. The recurrences as AVNRT in 2 of 25 symptomatic patients occurred in the first month after RFA. AVNRT in 4 of 41 and AVRT in 1 of 41 asymptomatic patients were induced within 3.5 months and 15 months, respectively.Conclusion:TEEPS seems to be a valuable screening and diagnostic method for the determination of recurrence in symptomatic and asymptomatic children who underwent successful RFA.
