Abstract Objective To explore the application value of transesophageal electrophysiologic study (TEEPS) in the diagnosis and treatment of patients with paroxysmal supraventricular tachycardia (PSVT). Methods We retrospectively analyzed the electrophysiological data of 371 patients who had been suspected with PSVT due to palpitation and had undergone TEEPS. The detection of tachycardia by using TEEPS was analyzed. The sensitivity, specificity and accuracy rate of TEEPS in contrast to intracardiac electrophysiologic study (IEPS) were statistically calculated. Results There were 45.55% (169/371) of the patients diagnosed with tachycardia by TEEPS, and 81.07% (137/169) of them were diagnosed with atrioventricular node reentrant tachycardia (AVNRT) and atrioventricular reentrant tachycardia (AVRT). Exercise combined with S1S1 and S1S2 stimulations can significantly increase the detection rate of PSVT. With IEPS as the diagnostic gold standard, the diagnostic accuracy rate of TEEPS for PSVT was 95.54% (107/112). The sensitivity and specificity of TEEPS for AVNRT was 100% and 92.31%, respectively; the sensitivity and specificity of TEEPS for AVRT was separately 93.18% and 98.53%; the sensitivity and specificity of TEEPS for atrial tachycardia was separately 71.43% and 100%. Conclusion TEEPS proves to be safe and effective, which could increase the diagnostic rate of PSVT, and has relatively high diagnostic sensitivity and specificity for a variety of arrhythmias.
