老年人埋藏永久起搏器的经验

CLINICAL EXPERIENCES IN OLD INDIVIDUALS WITH PERMANENT CARDIAC PACEMAKERS

报告29例(53次)缓慢心律失常的老年人(≥60岁)经静脉埋藏永久起搏器的结果,就埋藏永久起搏器患者缓慢心律失常类型,病因,适应证,随访等方面进行分析。

29 aged patients of transvenous endocardial pacemaker implantation have been performed during 1981-1988. Elderly group consisted of 29 cases with 19 males and 10 females with age ranging from 60-86 years. The indications for permanent pacing in this series included. (1) Sinus bradycardia (2 cases), (2) Sinus bradycardia, sinus arrest and/or sinoatrial block (2. cases), (3) Brady-tachyarrhythmia (It cases), (4) Bifaseicular block (2 cases), (5) Trifascicu lar block (3 cases), and (6) Complete AV block (9 cases). All 29 cases were symptomatic (syncopal attacks). They required permanent pacing. They have been followed up for 2 to 90 (average 39) months. The incidence of complications has been relatively low. A pacing mortality during the follow-up period was not seen in this series.A clinical assessment was made with emphasis on some special features in elderly individuals. In the elderly bradyarrbythmia was usually due to fibrosis and sclerosis of the conduc-tion system rather than to ischaemic heart disease. In the elderly the implantation of a pacemaker was indicated for any symptomatic bradycardia. Age was not a contraindication for permanent pacing
