Abstract

Three patients, two women and one man, aged 50.0 ± 9.8 years, who underwent catheter ablation for typical atrioventricular nodal re-entrant tachycardia, were studied during sinus rhythm. An electroanatomic system suitable for high-resolution mapping and recording of both bipolar and unipolar electrograms was used. Recording of potentials from the area of the right inferior extension was feasible in all patients with bipolar signals. Using unipolar signals, the electrical activity of the atrioventricular node was recorded in all patients. This preliminary report supports the existing evidence that the activity of the atrioventricular node and its right inferior extension can be successfully mapped in the electrophysiology lab.

房室结和右下结延伸的电解剖定位:来自一个病例系列的见解。
我们研究了3例(2女1男,50.0±9.8岁)因典型房室结再入性心动过速行导管消融治疗的患者。电解剖系统适用于双极和单极电图的高分辨率制图和记录。在所有双相信号患者中,右下延伸区电位记录是可行的。使用单极信号,记录所有患者房室结的电活动。这一初步报告支持了现有的证据,即房室结及其右下延部的活动可以在电生理实验室中成功地绘制。
