评价VDD起搏器远期心房感知功能的可靠性。 1 4例VDD起搏器病人 ,术后一周内每天记录心电图 ,术后32 .50± 1 3 .2 0个月时行Holter检查 ,检测过程中 ,让病人保持各种不同体位、做Valsalva动作、深呼吸、咳嗽及运动各2min ,并记录相应时间 ,手工检测 2 4h心房感知率。结果 :术后一周内 1 2例心房电极感知功能正常 ,1例于术后第 3天发生心房颤动 (简称房颤 ) ,经服用胺碘酮后恢复窦性心律 ,心房部分感知不良。 1例术后心房电极即无感知功能。Holter随访中 ,1 3例心房感知率为 88.98%± 2 8.35 % ,1例术后心房感知正常的病人 ,随访时动态心电图示持续房颤。结论 :对于绝大多数窦房结功能正常 ,因房室阻滞安装起搏器的病人 ,VDD起搏器远期心房感知功能比较可靠 Evaluate the reliability of the long-term atrial perception of the VDD pacemaker. 14 cases of VDD pacemaker patients, electrocardiogram was recorded every day within one week after operation, Holter examination was performed at 32 .50 ± 13 .2 months after operation. During the test, the patient was kept in various positions and performed Valsalva action , Take a deep breath, cough and exercise each 2min, and record the corresponding time, manual detection of 24h atrial awareness. Results: A week after surgery, 12 cases of atrial electrode sensory function was normal, 1 case of atrial fibrillation occurred on the 3rd day after operation (atrial fibrillation), sinus rhythm was restored after taking amiodarone, and part of the atrium was badly perceived. A case of postoperative atrial electrode that is no sense of function. Holter follow-up, 13 cases of atrial awareness was 88.98% ± 2 8.35%, 1 patient with normal atrial sensation after follow-up, dynamic ECG showed atrial fibrillation. Conclusion: Long-term atrial sensing of VDD pacemakers is reliable for most patients with normal sinus node function and pacemaker placement due to atrioventricular block
