摘　　要：为了探讨双心房起搏治疗快速房性心律失常的方法 ,并对其疗效进行评价 . 5例均行冠状窦内起搏左房 .其中 4例选择冠状窦专用电极 ;1例选择普通心室电极 ,双心房导线通过一个Y接头连接DDD起搏器的心房部分 ,行AAT双房起搏 . 4例冠状窦电极置于其中段 ,1例置于其远端 .术中阈值测试 ,输出电压为 0 6～ 2 2V ,阻抗 380～ 70 0Ω ,P波振幅 2 6～ 5 1mV .随访 4～ 18个月 ,4例有效 ,其中 3例疗效明显 ,有效率 80 % .结果表明To investigate methods of treating atrial tachycardia by arrhythmias by biatrial pacing and assessments of efficacy.Left atrial pacing had been done in coronary sinus in 5 cases, including 4 cases in specific electrodes of coronary vein sinus l case in ordinary ventricular electrode. Biatrial leads were connected to atrial port of DDD pacemaker by a “Y” type connector .The pacing mode was AAT.Results: 4 coronary sinus leads were put in middle part and l in distal part. We tested threshhold, sensitivity and impedance in operations. The follow-up time was 4-l 8 months. Biatrial pacing had an effect on 4 cases and had significant effects on 3 cases. The effective rate was 80 percent.Conclusion:Biatrial pacing can treat atrial tachycardia arrhythmias effectively for intraatrial block.
