摘要
目的 观察三腔双心室起搏治疗充血性心力衰竭效果。方法 患者男性 2例 ,女性 1例 ,平均年龄 5 7岁 ,为充血性心功能衰竭伴左束支阻滞 ,植入三 (四 )腔双心室起搏器。左心室起搏通过冠状静脉窦植入 2 187或 2 188电极导线 ,置于心后静脉起搏左心室 ,左右心室电极导线通过 Y形转接器与双腔起搏器连接。结果 双心室起搏并辅以合适的 AV延迟后 ,患者心力衰竭症状明显改善 ,N YHA分级从 ～ 级改善至 级 ,二尖瓣返流明显减少。结论 初步临床应用提示 。
Objective To observe the effect of biventricular pacing to treat congestive heart failure. Method The patients,2 male,1 female,57 years old on average,with refractory congestive heart failure and left bundle branch block,were implanted with three or four chamber biventricular pacemaker.The 2187 or 2188 coronary sinus leads were inserted to the branch of coronary sinus to pace left ventricle. Results The heart function was significantly improved after biventricular pacing at optimized A V delay.The NYHA class of cardiac function increased from Ⅲ～Ⅳ to Ⅱ. Conclusion The biventricular pacing is an effective method to treat patients with congestive heart failure with left bundle branch block.
