摘要
目的:探讨异丙肾上腺素联用阿托品对判定阵发性室上性心动过速(PSVT)消融终点的意义。方法:219例PSVT 患者在消融后联合应用丙肾上腺素和阿托品进行心内电生理检查,以不能诱发PSVT 为消融终点。结果:219 例患者消融后以静脉应用异丙肾上腺素和阿托品后确定消融终点,结果随访3～36个月,均无PSVT 复发。结论:对于射频消融术治疗阵发性室上性心动过速,以联合使用异丙肾上腺素和阿托品后心内膜电刺激,不能诱发阵发性室上性心动过速为消融终点是杜绝复发的终点。
Objective ： To assess clinical signification of combinative administration of isoproterenol and atropine for determine ablation end points of paroxysmal supraventricular tachycardia （PSVT）. Methods： A total of 219 patients with PSVT were performed conventional electrophysiological study （EPS） and radiofrequency catheter ablation （RFCA）.It was defined as ablation end opoint of PSVT that after combinative administration of isoproterenol and atropin the point can＇t induces tachycardia by endocardium electrical stimulation. Results ： According this method to determine ablation end point of 219 patients, there was no recurrence of PSVT in follow-up of 3-36 months. Conclusion： The method of combinative administration of isoproterenal and atropine to determine end point of ablation may avoid recurrent of PSVT.
