心房起搏心房感知抑制型起搏器(AAI),其特点是电极置于心房,刺激心房起搏,又能感知心房的自身激动而抑制起搏器发放脉冲.适合于房室传导功能正常的病态窦房结综合征(SSS)病人.由于它能保持房室顺序收缩,属于生理性起搏.故近年来已日益受到国内外学者的重视,自1989年～1990年10月我院成功地对7例SSS患者安置了AAI起搏器,取得满意效果,现报道如下.1 临床资料男4例,女3列,年龄52～67岁,平均57岁,7例患者经临床、电生理检查均符合病态窦房结综合征诊断,均有不同程度黑朦或晕厥等症状,病程平均6.1年.2例有阵发性心房纤颤史,电生理检查房室传导功能正常,
Atrial Pacing Atrial Sense Suppression Pacemaker (AAI), which is characterized by the electrode placed in the atrium to stimulate the atrial pacing, but also to sense the atrial activation itself and inhibit the pacemaker pulse delivery. Suitable for atrioventricular conduction function Sick sinus syndrome (SSS) patients because it can maintain atrioventricular order contraction, is a physiological pacemaker, it has been increasingly in recent years the attention of scholars at home and abroad, from 1989 to 1990, our hospital successfully 7 cases of SSS patients placed AAI pacemaker and achieved satisfactory results are reported as follows.1 Clinical data of 4 males and 3 females, aged 52 to 67 years, mean 57 years, 7 patients by clinical, electrophysiological examination Are in line with the diagnosis of sick sinus syndrome, both have different degrees of darkness or syncope and other symptoms, duration of an average of 6.1 years .2 cases of paroxysmal atrial fibrillation history, electrophysiological examination of atrioventricular conduction function is normal,
