摘　　要：目的研究右束支传导阻滞(RBBB)的心力衰竭患者对心脏再同步化治疗(CRT)的反应。方法选择16例RBBB且行CRT治疗的心力衰竭患者,通过超声心动图比较其术前与术后6个月的左心室大小,左心室射血分数,二尖瓣反流面积,心室间及左心室同步性。结果术后6个月,13例息者的平均左心室收缩末内径[(43.2±4.5)mm]、左心室舒张末内径[(54.1±5.8)mm]小于术前[(54.8±6.4)、(63.4±8.2)mm](P<0.05),心室间、左心室内收缩同步性[LVPT-RVPT(23.7±8.2)ms、TS-SD-12(31.5±9.7)ms]较术前[LVPT-RVPT(41.4±10.5)ms、TS-SD-12(52.7±11.2)ms]改善,差异有显著统计学意义(P<0.01)。但另3例患者的上述指标较术前无显著提高。结论部分合并RBBB的心力衰竭患者CRT可能获益。Objective To evaluate the effects of cardiac （HF） and right bundle branch block （RBBB）. Methods resynchronization therapy（CRT） on patients with heart failure Left ventricular size, left ventricular ejection fraction, mitral regurgitation, the synchronicity of interventricular and left ventricular contractions were measured by echocardiography before and 6 months later after CRT in 16 patients with HF and RBBB. Results Left ventricular end systolic diameter, end diastolic diameter, LVPT-RVPT and TS-SD-12 decreased significantly from（54.8 ± 6.4）mm, （63.4 ± 8.2）mm, （41.4 ± 10.5）ms and （52.7 ±11.2）ms before to （43.2 ±4.5）mm, （54.1 ± 5.8）mm, （23.7 ± 8.2）ms and （31.5 ± 9.7）ms at 6 months after CRT, respectively, in 13 patients （P〈0.05 or 0.01）. These parameters were not improved in another 3 patients. Conclusion CRT may be beneficial to some patients with HF and RBBB.
