研究目的:

1.测量健康志愿者AFI参数的参考值范围; 2.比较LBBP术后电、机械同步性及左室心肌做功是否可以达到正常的生理状态,是否优于RVSP; 3.探讨Lot-CRT植入后的临床疗效、反应率及超反应率, Lot-CRT术后的电、机械同步性、左室大小及收缩功能是否优于BiV-CRT; 4.观察Lot-CRT有反应的患者从Lot-CRT程控到单纯LBBP后,心脏的电、机械同步性、左室的大小和收缩功能是否有变化。  

Objectives of Study:

1. Measure the reference value range of AFI parameters in healthy volunteers; 2. Compare whether electrical and mechanical synchrony and left ventricular myocardial work after LBBP surgery can reach normal physiological states, and whether it is superior to RVSP; 3. Explore the clinical efficacy, response rate, and super-response rate after Lot-CRT implantation, and whether electrical and mechanical synchrony, left ventricular size, and systolic function after Lot-CRT are superior to BiV-CRT; 4. Observe whether there are changes in cardiac electrical and mechanical synchrony, left ventricular size, and systolic function in patients who responded to Lot-CRT after switching from Lot-CRT pacing to simple LBBP.
