由《起搏与心脏》编辑部与西安医科大学心血管病研究所共同举办的“AAI起搏专题研讨会”于1991年5月6日在西安召开。来自全国18个省的近100名代表参与了讨论。陈灏珠、孙瑞龙、朱中林、杨鼎颐、沈潞华、陆再英、程心培、钱剑安、胡大一等教授出席并指导了这次研讨会。大会就AAI起搏器植入技术、血流动力学改变及其优点、适应证和禁忌证、随访指标等问题进行了热烈讨论。现将讨论情况予以介绍。一、AAI起搏器植入技术 (一)心房电极植入 AAI起搏器植入的关键是心房电极的放置。目前,通用的心房电极有两种,即螺旋电极与J形电极。国际上美国和西欧多选用J形电极,而东欧则多选螺旋形电极。国内选用的亦多为J形电极。螺旋形电极尖端呈螺旋形,无预制的弯度,
The AAI Pace Symposium co-sponsored by the Editorial Department of Pacing and Heart and Xi’an Medical University Institute of Cardiovascular Diseases was held on May 6, 1991 in Xi’an. Nearly 100 delegates from 18 provinces across the country participated in the discussion. Chen Haozhu, Sun Ruilong, Zhu Zhonglin, Yang Dingyi, Shen Luhua, Lu Zuoying, Cheng Xinpei, Qian Jianan and Hu Dayi and other professors attended and guided the seminar. Conference on AAI pacemaker implantation technology, hemodynamic changes and its advantages, indications and contraindications, follow-up indicators and other issues were heated discussions. The discussion will be introduced. First, the AAI pacemaker implantation (a) atrial electrode implantation AAI pacemaker implantation is the key to the placement of the atrial electrode. At present, there are two kinds of common atrial electrodes, namely, spiral electrodes and J-shaped electrodes. Internationally, the United States and Western Europe mostly use J-shaped electrodes, while Eastern Europe uses more spiral electrodes. Domestic selection of mostly J-shaped electrode. Spiral electrode tip is spiral, without precast curvature,
