室上性心动过速的食管心房标测与心内膜标测定位价值的对照分析

Comparative Analysis of localization Value of Supraventricular Tachycardia by Esophagoatrial Detecting and by Endocardial Detecting

旨在评价食管心房标测在室上性心动过速中的定位价值对３０例室上性心动过速（ＰＳＶＴ）患者射频消融术前行食管心房标测测量ＲＥ—Ｐ′Ｅ及Ｐ′Ｖ１—Ｐ′Ｅ时距，与腔内电生理及消融靶点对照结果发现左右两侧房室旁道（ＡＰ）并房室折返性心动过速（ＡＶＲＴ）与房室结折返性心动过速（ＡＶＮＲＴ）的ＲＥ—Ｐ′Ｅ及Ｐ′Ｖ１—Ｐ′Ｅ时距各具特征，相互无重叠。

Our purpose was to evaluate the localization value of supraventricular tachycardia by sesophagoatrial detecting. Thirty cases of supraventricular tachycardia were given before receiving radiofrequency current ablation the esophagoatrial detection for RE-P'E and P'v1-P'E time intervals, which were compared with the electric physiologic and ablation targets in the chest. The outcomes revealed that, among the left-right atrioventricular passages (AP), the astrioventricualr reentrant tachycardia (AVRT), and the atrioventricular nodal reentrant tachycardia (AVNRT), RE-P'E and P'v1-P'E time intervals had their own characters and did not overlap with one another. These characters were of certain positive value for the differentiate of the above three and the diagnostic coincidental rate was 93% .
