摘要
目的 探讨冠状窦起搏电极行双心房起搏的有效性、安全性 ,并观察双心房同步起搏对伴房内/房间传导阻滞的阵发性快速房性心律失常的临床应用效果。方法 为7例病态窦房结综合征 ,阵发性房颤伴房内/房间传导阻滞的患者植入冠状窦起搏电极、常规右心耳及右心尖电极 ,行双心房同步起搏。结果 冠状窦起搏电极均成功植入 ,术后双房同步起搏可使P波时限缩短 ,部分地预防房颤发作。本组术后3月脱位1例 ,予成功复位。结论 应用冠状窦起搏电极行双心房同步起搏是安全有效的 ;双心房同步起搏对伴有房内传导阻滞的阵发房颤有一定的疗效。
砄bjective To evaluate the clinical efficacy and safety of coronary sinus(CS) pacing lead in the biatrial synchronic pacing, and the clinical efficacy of treating and preventing paroxysmal atrial tachyarrhythmias(atrial tachycardia, atrial flutter atrial fibrillation). Methods seven patients suffered from sick sinus syndrome(SSS) with interatrial or intratrial conduction block(IACB)and paroxysmal atrial fibrillation were implanteda tri-chamber pacemaker with biatrial synchrony. Three leads were placed into CS, right ventricle apex(RVA) and right auricle(RA) respectively. Results All of CS lead were implanted successfully. The duration of P wave with biatrial AAT mode was shortened. The partial effective rate for preventing atrial fibrillation was 66.7% while the total effective rate was 100%. One case was dislocated after three months of implantafion. Conclusion The implanting of CS pacing lead in biatrial synchronic pacing mode was safe with good efficacy. Biatrial synchronic pacing mode was effective in treating and preventing paroxysmal atrial fibrillation with interatrial or intratrial conduction block. 〔
