【 摘要】 目的 了解心房起搏的远期效果及并发症。方法 对66例心房起搏患者进行了临床、心电图、起搏参数的定期随访，随访时间为38±2.04个月。结果 所有患者术后生活质量明显改善，无1例心衰及死亡。术中、术后心电参数符合起搏要求。16例术前阵发性心房颤动者，术后发作频率及时间明显减少(P<0.01、0.05)。15例(22.7%)发生过感知，电极移位4例(6.1%)，房室传导阻滞2例(3.0%)。结论 心房起搏是一种安全的起搏方式，可保持正常的房室收缩顺序功能及血流动力学效果，而明显优于心室起搏。

     【Abstract 】 Objective To study thelong-term results and complications of atrial pacing.Methods A long-term follow-up survey was carried out in 66 cases of atrialpacing by clinical examination, electrocardiography, DCG and pacing parametermeasurements. The mean follow-up time was 38±2.04 months.Results The life quality of all patients was improved significantly,without heart failure or death. The pacing parameters were kept with the requirement ofpacemaker during and after operation. In 16 patients the frequency and duration ofparoxysmal atrial fibrillation were decreased markedly compared with those before atrialpacemaker implantation (P<0.01 and P<0.05). Oversensing occurred in 15 patients(22.7%), Lead dislocation in 4 (6.1%), ant A-V conduction block in two (3%). Conclusion AAI is a reliable and safe mode of pacing, and provides normal A-Vsequence and hemodynamics. Thus, atrial pacing is apparently superior to ventricularpacing.
