Abstract：Objective To investigate the value of transesophageal electrophysiologic study (TEEPS) and intracardiac electrophysiological study (IEPS) in diagnosing supraventricular tachycardia (SVT). Methods IEPS was performed in 197 patients who had undergone TEEPS to induce and terminate SVT. The results were comparatively analyzed. Results IEPS diagnosis results are considered as the gold criteria for SVT, and applied to verify the diagnostic accuracy of TEEPS. By TEEPS, the diagnostic accuracy rate of atrioventricular nodal reentrant tachycardia (AVNRT) is 97.1%, the diagnostic accuracy rate of atrioventricular reentrant tachycardia (AVRT) is 94.1%, and the diagnostic accuracy rate of atrial tachycardia (AT) is 100%. The detection rate of AVNRT by TEEPS and IEPS are separately 73.2% and 72.3% while the detection rate of AVRT by TEEPS and IEPS are both 26.7%, without statistically significant differences (P>0.05). Spontaneous or stimulation induced tachycardia during TEEPS could be terminated by transesophageal atrial pacing except for AT. Conclusion TEEPS has a relatively high application value in the determination of SVT mechanism, location of atrioventricular accessory bypass and termination of tachycardia. As a routine screening tool before radiofrequency ablation, TEEPS is capable of shortening operation time, and reduce operation trauma and economic burden.
