病竇綜合徵患者AAI 和 VVI 起搏的遠期隨訪分析

To analyse and compare the long-term results of patients with sick sinus syndrome (SSS) after AAI pacing and VVI pacing. The patients with SSS were treated with atrial pacing (AAI group, n=140)and ventricular pacing (VVI group, n=43). A long-term follow-up survey was carried out by clinical examination, electrocardiography and Holter. Results: The follow-up time was 52±4.3(6~144) months. Only one case developed intermittent Mobitz type I atrioventricular block (AVB) after AAI pacing. The rates of atrial arrhythmias, persistent atrial fibrillation, cerebral embolism and cardiogenic death were significantly higher in VVI group than those in AAI group(39.53% vs 5.71%,18.60% vs 1.43%,9.3% vs 0.71%,11.63% vs 0.71%, all P＜0.01). The rate of atrial arrhythmias in VVI group was obviously increased(39.53% vs 18.60%,P＜0.01), in AAI group was obviously decreased(5.71% vs 18.57%, P＜0.01). None was found the lead dislocation. Conclusion: The frequency of the long-term AVB and lead dislocation was so lower in AAI Pacing. The frequency of atrial arrhythmias, cerebral embolism and cardiogenic death was lower in AAI Pacing than those in VVI Pacing.
