AIM To evaluate the influence of pacing in right ventricular septum (RVS) and right ventricular apex (RVA) on pacingparameter 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 pacingparameter were optimized dynamically.
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.
