三度房室传导阻滞(Ⅲ°AVB)和病态窦房结综合征(SSS)是两种严重过缓型心律失常,可发生阿斯综合征,威胁病人生命安全,目前国外、国内均无有效药物治疗。心脏起搏器是生物医学工程迅速发展和较成熟的一种产品,对药物治疗无效的过缓型、过速型和过缓过速型心律失常病例,采用心脏起搏器治疗往往能取得较好疗效。我院自1987年2月～1989年2月用埋藏式心脏起搏器(简称起搏器)治疗7例严重过缓型心律失常病人,现将一般情况及点滴体会报告如下。 1 原理心脏起搏器由起搏电极、导管和脉冲发生器三部分组成,体积小,重量仅45～55g。起搏器内有集成电路和锂电池,钛合金外壳,激光封闭,用脉冲电流刺激心脏,以维持或控制心脏节律或改善心脏的
Third-degree atrioventricular block (Ⅲ ° AVB) and sick sinus syndrome (SSS) are two kinds of severe bradycardia arrhythmia, which can lead to Aspergillus syndrome and threaten the life safety of patients. At present, there are no foreign or domestic Effective medical treatment. Pacemaker is a rapid development and more mature biomedical engineering products, drug treatment ineffective bradycardia, tachycardia and tachyarrhythmia cases, the use of pacemakers often can get more treatment Good effect. Our hospital from February 1987 to February 1989 with the implanted pacemaker (referred to as pacemaker) treatment of 7 cases of severe bradycardia arrhythmia patients, now the general situation and bit by bit experience report as follows. 1 Principle Pacemaker pacemaker electrode, catheter and pulse generator consists of three parts, small size, weighing only 45 ~ 55g. Pacemakers have integrated circuits and lithium batteries, titanium alloy shell, laser-enclosed, pulsed current stimulation of the heart to maintain or control heart rhythm or improve heart
