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.
三名患者，两名女性和一名男性，年龄为50.0±9.8岁，因典型房室结折返性心动过速接受导管消融治疗，在窦性心律期间进行了研究。使用了一种适用于双极和单极电图的高分辨率标测和记录的电解剖系统。在所有具有双极信号的患者中，均可行从右下延伸区域记录电位。使用单极信号，在所有患者中均记录到了房室结的电活动。本初步报告支持现有证据，即房室结及其右下延伸区域的活动可在电生理实验室中成功标测。
