CLINICAL SIGNIFICANCE OF TRANSESOPHAGUS Pv1-Pe ON DIAGNOSIS OF VARLDUS TYPES OF SUPRAVENTRICULAR TACHYCARDIA

Radiofrequency catheter ablation(RFCA)were performed in 142 patients with paroxysmal supraventricular reentranltechycardia(PSVT),including 67 patients of left side accessory pathway,20 patients of right side accessory pathway,48 patients with slow-fast type atrioventricular nodal reentrent tachyardia(AVNRT),and 7 patients with strialreetrant tachycardia(ART),The average of age was 40.9±13.8 years old(14-72ys).Transesophagus and intracardiacelectrophysiologic studies were carried out in all patients,and the Pv1-Pe,R-Pe were compared in these two methods.In order to assess the clinical significant of Pvl-Pe.R-Pe in diagnosis of various types of supratachycardia anddifferent accessory pathway.ResultsConclusionsThis article analysed the relations of the Pvl-Pe,R-Pe and the Δ A,V-A in all 142 patients with SVT.It is suggestthat AVRT with anterograde,Pvl-Pe was more than 25 ms,R-Pe more than 75ms,with the exception of RSAP Pvl-Pewas 0,R-Pe more than 75ms.In petients with ART,Pvl-Pe more than 25ms,R-Pe more than 150ms and R-Pe morethan Pe-R.AVNRT group Pvl-Pe less than 25ms,R-Pe less than 70ms.These are very sensitive and specific in makingthe diagnosis of SVT,It is also useful that conceled assessory pathway site can be decided,according to the trend ofchange of Pvl-Pe and R-Pe.We concluded that tranesophagus Pvl-Pe and R-Pe hold great value on diagnsis ofvarious types of supraventricular
