【摘要】 目的　观察双房同步起搏技术对伴有房间传导阻滞的阵发性快速性房性心律失常的疗效。方法　病态窦房结综合征合并房间传导阻滞的阵发性快速性房性心律失常患者 7例 ,男 4例、女 3例 ,年龄 5 8～ 78岁。其中 4例行双房起搏 (AAT) ,3例行双房右室三腔起搏 (DDD) ,经穿刺左锁骨下静脉插入右房、右室和冠状静脉窦起搏电极导线 ,分别用于起搏右房、右室和左房。结果　起搏器及电极导线均顺利植入 ,未发生任何并发症。冠状静脉窦电极顶端距冠状静脉窦口 2 5 - 3 5cm ,P波振幅为1 6 - 5 5mV、阻抗 6 2 4 - 80 8Ω、单极起搏阈值 0 5 - 0 7V。随访 2 - 31个月 ,7例均健在 ,房性心律失常的临床发作得到明显控制。结论 :双房同步起搏技术是房间传导阻滞合并快速房性心律失常的有效预防和治疗方法更多还原

【Abstract】 Objective To observe the efficacy of biatrial synchronous pacing to prevent and treat paroxysmal rapid atrial arrhythmia accompanied with interatrial conduction block.Methods 7 patients,4 males and 3 females,(58～78)-years-old,with sick sinus syndrome and paroxysmal rapid atrial arrhythmia accompanied with interatrial conduction block were implanted with biatrial (AAT)pacemaker (4 cases)or biatrail trichamber(DDD) pacemaker (3 cases).Three leads were inserted into right auricle,right ventricle and coronary sinus through perforating left subclavicular vien to pacing right atrium,right ventricle and left atrium,respectively.Results All leads and pacemaker were implanted favorably and no complications were happened.The distance from coronary sinus ostium to coronary sinus lead distal was 2.5～3.5cm.The amplitude,impedance and unipolar pacing threshold of the P wave of CS lead was 1.6～5.5mV,624～808Ω and 0.5～0.7V,respectively.All 7 patients were healthy and clinical attacks of atrial arrhythmias were significantly controled.Conclusion Biatrial synchronous pacing is a effective way to prevent and treat paroxysmal rapid atrial arrhythmia accompanied with interatial conduction block.更多还原
