【摘要】 目的:探讨窦性心律疏导术治疗心房颤动的临床应用价值。方法:18例风湿性心脏病合并慢性心房颤动的患者在行二尖瓣置换术的同时行窦性心律疏导术,其所有切口都平行于传导束和心房动脉。结果:术中病人均自动恢复窦性心律。术后2周内12例患者心功能达Ⅰ～Ⅱ级;多普勒检查可见二尖瓣口出现明显的A 峰,表明左房运输功能已恢复。随访3月到6年,16例维持永久窦性心律,2例在药物控制下维持间断的窦性心律。结论:窦性心律疏导术对于二尖瓣置换术几乎不增加手术时间,也不会增加危险性,但可获得很好的窦性心律转复律。更多还原

【Abstract】 To evaluate the role of sinus impulse-dredging procedure(SPDP)treatment for arial fibrillation. Methods:A total of 18 patients with rheumatic heart disease and atrial fibrillation were performed mitral valve re- placement,simultaneously underwent SPDP.Every incision of SPDP parallels natural impulse conduction pathway and atrial artery.Results:All patients regained sinus rhythm during operation.Two weeks postoperation the heart func- tion of the 12 patients recovered to Ⅰ～Ⅱ(NYHA).Atrial transport function regained in two weeks.All the pa- tients were followed up from 3 months to 6 years.Except 2 patients were maintained intermission sinus rhythm with medication,all patients were maintained sinus rhythm.Conclusion:Sinus impulse-dredging procedure is safe and easy to perform,but may mostly regain sinus rhythm.更多还原
