摘要
目的评价双心室起搏治疗充血性心力衰竭的临床疗效。方法3例伴左束枝阻滞或室内阻滞的难治性充血性心力衰竭患者,男2人,女1人,平均年龄67岁,所有患者植入三腔双心室起搏器,左室电极经冠状窦置入冠状静脉侧支或后侧支。结果手术全部成功。三名患者于植入后临床症状明显改善,6分钟步行距离延长,体表心电图QRS时限由166±25ms缩短至110±8.2ms。随访10～18个月,超声心动图示左室射血分数由32.6±3.3%增至44.6±5.2%。但二例病人在随访期间,死于心室颤动。结论双心室起搏可以改善难治性充血性心力衰竭患者的临床症状,提高生活质量,改善心脏功能。
Objective To evaluate the clinical efficacy of biventficular pacing in patients with congestive heart failure. Methods There are 3 patents, male in 2 and female in 1, mean age of 67 years old, with refractory congestive heart failure, and left bundle branch block or intraventricular delay. All patents received three chamber biventricular pacing and left ventficular pacing lead was inserted into the postero-lateral or lateral branch of cardiac vein via coronary sinus to pace the left ventricle. During the period of follow-up, unfortunately, two patients with ischemic myocardiography died of sudden cardiac death. Results After biventricular pacing, the clinical symptoms were markedly improved in all patients. The mean QRS duration was decreased from 166±25ms to 110±8.2ms. The LVEF was increased from 32.6% to 44.6±5.2% and LVDD decreased from 70.6 mm to 63.3mm in eehocardiography. The NYHA class of the patients was improved from Ⅲ-Ⅳ to Ⅰ- Ⅱ. Conclusions The biventricular pacing may improve the heart function of patients with refractory congestive heart failure and raise the quality of life.
