食管与心内电生理检查诊断室上性心动过速的对比研究

目的探讨食管电生理检查对室上性心动过速(SVT)诊断及分型的准确性。方法对192例SVT患者的食管电生理检查和心内电生理检查结果进行对照比较。结果2种电生理检查对房室结双径路(DAVNP)、房结折返性心动过速(AVNRT)、房室折返性心动过速(AVRT)、常见的顺向型房室折返性心动过速(OAVRT)、左侧房室旁道(LAP)、右侧房室旁道(RAP)的诊断率相一致,差异无统计学意义(P>0.05),但食管电生理检查对间隔旁道(SAP)参与的AVRT与房性心动过速(AT)的诊断率较心内电生理检查低(P<0.05)。结论食管电生理对常见SVT的诊断及分型与心内电生理有相似的价值,且具有无创、简便、费用低等特点。

Control study of diagnosis of supraventricular tachycardia by esophageal electrophysiology and intracardiac electrophysiology

Objective To investigate the accuracy of diagnosis and classification of supraventricular tachycardia(SVT)by esophageal electrophysiology.Methods Results of esophageal electrophysiology and intracardiac electrophysiology in 192 patients with SVT were compared.Results Diagnosis of dual atrioventricular nodal pathway(DAVNP),atrioventricular nodal reentrant tachycardia(AVNRT),left accessory pathway(LAP) and right accessory pathway(RAP) as well as orthodromic atrioventricular reentrant tachycardia(OAVRT) were no significant difference between these two electrophysiology study;but diagnostic rate of septal AP(SAP) mediated AVRT and atrial tachycardia(AT) by esophageal electrophysiology were lower than that by intracardiac electrophysiology.Conclusion Esophageal electrophysilolgy has the similar accuracy of diagnosis and classification of common SVT to intracardiac electrophysiology,and has advantages of noninvasiveness,simplicity and low cost,etc.
