尽管采用各种抗心律失常药治疗房颤(AF),但仍有病人症状难以控制,工作及生活受到严重影响。AF的持久存在依赖于心房异位起搏点不断发放一定数量的冲动,因此心房表面积的缩小可减少异位冲动的产生。作者设计了一种通路手术,总结了1987年4月至1989年12月最初20例药物难以控制的阵发性AF病人采用通路手术的经验。其中男性14例,女性6例,年龄32～69岁。患者阵发性AF病史至少3年,发作时出现头晕、丧失工作能力、极度疲劳。发作间
Despite the use of various antiarrhythmic drugs in the treatment of atrial fibrillation (AF), the patient’s symptoms are still difficult to control and their work and life are severely affected. The persistence of AF relies on the constant release of a certain amount of impulses from the atrial ectopic pacemaker so that reduction of the atrial surface area reduces the incidence of ectopic impulses. The authors designed a pathway surgery that summarizes the experience with access surgery in the first 20 patients with paroxysmal AF who were refractory to drug control between April 1987 and December 1989. Including 14 males and 6 females, aged 32 to 69 years. Patients with paroxysmal AF history of at least 3 years, the onset of dizziness, loss of ability to work, extreme fatigue. Between episodes
