笔者安置心房按需起搏(AAI)13例,占同期安置起搏器数的28%.经平均41个月的随访,13例患者术前心动过缓引起的晕厥、黑蒙等症状均消失,运动耐力增强;术前8例伴有阵发性房颤和(或)短阵房速,安置AAI后5例消失,2例发作次数明显减少,发作时间短暂,无需用药,1例发作次数仍较多,仍需服心律平预防发作.3例伴有室早患者安置AAI后未见室早减少.随访期,1例发生感知不良,1例发生起搏不良,均经程控解决.无1例发展为慢性房颤和房室传导阻滞.
The author placed 13 patients with atrial appendage pacing (AAI), accounting for 28% of the pacemaker placement in the same period.After an average of 41 months of follow-up, thirteen patients with preoperative bradycardia caused syncope, amaurosis and other symptoms are disappeared , Exercise tolerance increased; preoperative eight patients with paroxysmal atrial fibrillation and (or) atrial tachycardia, AAI after placement disappeared in 5 cases, 2 cases significantly reduced the number of seizures, episodes of time short, no medication, 1 episode Still more need to take the prevention of seizures of ventricular tachycardia.3 cases of patients with early ventricular involvement of AAI did not see early reduction.Patient follow-up period, 1 case of poor perception, 1 case of poor pacing were controlled by the program. One patient developed chronic atrial fibrillation and atrioventricular block.
