本文介绍了经食道心房调搏诊断房室结双通道的方法。其诊断依据为:1.不连续的起搏周期(SS)、房室传导时间(SR)曲线,或不典型文氏现象;2.慢通道(SP)、快通道(FP_1)传导时间相差≥60ms;3.心房调搏能诱发和中止室性心动过速。房室双通道的常见折返方式为SP型,食道心电图上表现PR/RP>1。
This article describes the transesophageal atrial pacing diagnosis of atrioventricular node dual channel method. The diagnostic criteria are as follows: 1. Discontinuous pacing cycle (SS), atrioventricular conduction time (SR) curve or atypical Wen’s phenomenon; 2. Difference between conduction time of slow channel (SP) and fast channel (FP_1) ≥ 60ms; 3 atrial pacing can induce and terminate ventricular tachycardia. Atrioventricular dual channel common reentry approach for the SP type, esophageal ECG performance PR / RP> 1.
