AIM To evaluate the influence of pacing in right ventricular septum (RVS) and right ventricular apex (RVA) on pacing parameter and biventricular electrical synchrony.
目的评估右室间隔部起搏和右室心尖部起搏对起搏参数和双心室电同步性的影响。
Cases of CRT group were given right atrium and biventricular or pure biventricular pacing, and received strict follow-up and the pacing parameter were optimized dynamically.
CRT组施行右房双室或单纯双室起搏并动态随访、优化起搏参数，同时两组患者皆给予正规的抗心衰药物治疗。
Conclusions: Biventricular pacing therapy can evidently improve the clinic symptom and relative heart function parameter in heart failure patients, enhance the living quality at meantime.
结论：双心室起搏可以较明显地改善顽固性心力衰竭患者的临床症状及相关心功能指标，能提高该类患者的生活质量。
