摘要
目的 观察双心室起搏对慢性心力衰竭患者心肺功能和生活质量的影响。方法 慢性心力衰竭伴室内传导阻滞患者 9例,比较双心室起搏前后患者超声心动图、心肺功能以及生活质量的变化。结果 双心室同步起搏后,患者左心室射血分数(% )由术前 21. 6±6. 7增加到 27. 3±5. 2(术后 3个月,P<0. 05)、29. 5±5. 4(术后 6个月,P<0. 05), 6分钟步行距离(m),由术前 320±97增加到 384±103(术后 3个月,P<0. 01)、413±110 (术后 6个月,P<0. 01),峰值氧耗量、摄氧效率斜率及每分通气量 /每分二氧化碳产生量斜率较术前均有显著增加。生活质量评分分别改善 30% (术后 3个月,P<0. 01)、28% (术后 6个月,P<0. 01)。结论 双心室起搏能有效改善慢性心衰患者心肺功能,增加运动能量,提高生活质量。
Objective To observe the clinical effects of biventricular Pacing on Patients with congestive heart failure(CHF).Methods 9 CHF patients with intraventricular block received biventricular synchronous pacing.The coronary sinus lead was inserted into the branch of coronary sinus to pace left ventricle.Echocardiogrghy,cardiopulmonary function and quality of life were evaluated.Results After biventricular synchronous pacing,the echocardiography parameters and cardiopulmonary parameters were significantly improved.The quality of life score improved by 30 percent (3 months later,P<0.01),28 percent (6 months later,P<0.01).Conclusion Biventricular pacing can improve cardiopulmonary function,exercise tolerance and quality of life in patients with congestive heart failure and intraventricular block.
