Objective To explore the diagnostic value of esophageal electrophysiological examination in the types of paroxysmal supraventricular tachycardia（PSVT）. Methods A total of 86 patients with suspected PSVT undergoing esophageal electrophysiological examination in the hospital were enrolled between March 2019 and March2021. The accuracy

sensitivity

specificity

negative predictive value

positive predictive value and Kappa value of esophageal electrophysiological examination in the diagnosis of PSVT were evaluated by Kappa consistency test.Results Kappa value of esophageal electrophysiological examination in the diagnosis of PSVT was 0.793. Compared with the golden standard of clinical diagnosis

accuracy

sensitivity

specificity

negative predictive value and positive predictive value of esophageal electrophysiological examination were 94.19%

95.83%

85.71%

80.00% and97.18%

respectively. Kappa value of esophageal electrophysiological examination in the diagnosis of PSVT types was0.816. Its diagnostic coincidence rate

missed diagnosis rate and misdiagnosis rate were 84.88%（73/86）

6.98%（6/86） and 8.15%（7/86）

respectively. The consistency between esophageal electrophysiological examination and clinical diagnosis was good in the diagnosis of PSVT. Conclusions The consistency between esophageal electrophysiological examination and clinical diagnosis is high in the diagnosis of PSVT types

which is of high specificity

sensitivity

accuracy and clinical application value.
