Abstract：Objective To discuss the clinical value of transesophageal atrial pacing (TEAP) to the diagnosis of paroxysmal supraventricular tachycardia (PSVT). Methods The patients (n=74) diagnosed as PAVT were given TEAP for inducing and stopping PAVT. The parameters of ECG of PSVT, including induced window, induced frequency and atrial-ventricular node refractory period, were recorded and analyzed. All the results compared with intracardiac electrophysiologic study (IEPS) . Results The parameters of induced window, induced frequency and atrial-ventricular node refractory period get from TEAP was correlated to those get from IEPS well (P<0.05). The coincidence rate of TEAP reached 83.8%(62/74) in PAVT diagnosis, and all induced PSVT were stopped by TEAP. Conclusion TEAP can effectively review the electrophysiological characteristics of PSVT with higher accuracy rate. It is worth of wide application in clinic.
