摘要
目的观察双心室起搏治疗顽固性心力衰竭的效果。方法对8例心功能Ⅲ~Ⅳ级,左心室射血分数≤35%,QRS波时限>0.12秒,伴有二尖瓣反流的顽固性心力衰竭患者行三腔双心室起搏治疗,观察术后心功能改善和生存质量改善情况。结果术后10天临床症状改善,6分钟步行距离增加,左心室射血分数增加,二尖瓣反流消失或缓解,左心室内径缩小,QRS波时减少。二个月后随访临床症状进一步改善,生活质量提高。结论双心室起搏治疗顽固性心力衰竭能缓解症状,改善心功能。
Objective To assess the clinical effects of biventricular pacing for patients with drug refractory heart failure. Methods Eight patients with dilated cardiomyopathy or ischemic cardiomyopathy were NYHA, class Ⅲ to Ⅳ .The left LVEF was≤35%, the QRS width was> 120ms.Biventricular synchronization pacing was performed after an atrio- biventricular pacemaker was implanted.The heart function was evaluated before and after up to days. Results The clincl symptoms of all patients were significantly improved.The NYHA class was improved by 1.2 grade and 6 - minute hall walk distance increased. LVEF was increased and degree of mitral regurgitation was decreased, QRS duration was significantly short-ended. Conclusion The biventricular pacing is likely associated with improvements of symptoms and heart function.
