摘　　要：目的:对比观察食道心房调搏术中基础刺激与基础刺激加异丙肾上腺素诱发室上性心动过速的诱发率。方法:302例临床拟诊阵发性室上性心动过速的患者被随机分成两组:基础刺激组(A组)151例,基础刺激加用异丙肾上腺素组(B组)151例,然后进行食道心房调搏检查。结果:B组的诱发成功率明显高于A组的(72.8%:41.1%,P<0.01)。同时B组患者中,房室结双径路的诱发成功率明显大于房室旁道(76.8%:57.5%,P<0.05)。结论:异丙肾上腺素能显著提高食道心房调搏术中阵发性室上性心动过速的诱发率,值得临床推广应用。Objective： To study the effect of isoprenaline in esophagcal atrial pacing induced paroxysmal supraventricular tachycardia （PSVT）. Methods： A total of 302 PSVT patients were randomly divided into underlying exitation group （group A, 151 cases） and underlying exitation ＋isoprenaline group （group B, 151 cases）, then esophagcal atrial pacing was performed. Results： Induced achievement rate of PSVT in group A was 41.1 %, it was significant low compared with that of group B （72.8%）, P〈0.01. The induced achievement rate of PSVT in dual A-V nodal pathways was 76.8 %, it was significant more than that of accessory atrioventricular pathweys （57.5 % ） in group B, P d0. 05. Conclusion： Isoprenaline can significantly increase induced rate of PSVT in esophagcal atrial pacing, it is deserve generalization.
