心脏起搏器用来治疗重度房室传导阻滞、窦房结功能衰竭已被证实是一种积极有效的办法。此类患者由于心室率过低,心、脑供血不足,极易发作心源性脑缺氧综合征(亦即阿-斯综合征),造成突然昏厥、抽搐,甚至死亡。据统计,用药物治疗的此类患者,一年的存活率仅40～50%;而应用起搏器,一年的死亡率可降到10%以下。随着制造和安装技 Cardiac pacemakers are used to treat severe AVG, and sinus node failure has proven to be a positive and effective method. Such patients due to ventricular rate is too low, heart, brain blood supply, vulnerable to onset of cardio cerebral anoxia syndrome (also known as Alzheimer’s syndrome), causing sudden fainting, convulsions and even death. According to statistics, such patients treated with drugs, the survival rate of only 40 to 50% a year; and the use of pacemakers, one year mortality can be reduced to below 10%.
