Abstract

Left bundle branch pacing (LBBP) is effective in patients with heart failure, left ventricular ejection fraction (LVEF) of ≤35%, and a widened QRS complex. LBBP leads to iatrogenic incomplete right bundle branch block (iRBBB). Bi-bundle pacing can resolve iRBBB, further narrowing the QRS duration, and may improve LVEF. ().

摘要

左束支起搏(LBBP)对心力衰竭、左心室射血分数(LVEF)≤35%且QRS波增宽的患者有效。LBBP会导致医源性不完全性右束支传导阻滞(iRBBB)。双束支起搏可解决iRBBB,进一步缩窄QRS时限,并可能改善LVEF。()
