Atrioventricular nodal reentrant tachycardia (AVNRT) and atrioventricular reentrant tachycardia (AVRT) were induced by esophageal pacing and their entrainment zones were examined in 20 patients. The results showed that the entrainment phenomenon, which was a common electrophysiological phenomenon in reentrant tachycardia, occurred during overdrive pacing in 19 cases (19/20). The entrainment zone was 10-70 (30.50 +/- 20.85, mean +/- s) ms. The tachycardias could not be interrupted by pacing within the entrainment zone, but they were terminated by burst pacing, with starting pacing cycle length shorter than the shortest entrainment cycle length.
通过食管起搏诱发20例患者的房室结折返性心动过速（AVNRT）和房室折返性心动过速（AVRT），并检查其拖带区。结果显示，拖带现象是折返性心动过速中常见的电生理现象，在19例（19/20）患者的超速起搏期间出现。拖带区为10 - 70（30.50±20.85，平均值±标准差）毫秒。在拖带区内起搏不能中断心动过速，但通过短阵猝发起搏可终止心动过速，起始起搏周期长度短于最短拖带周期长度。
