1.Left bundle branch block (LBBB) results in an altered pattern of left ventricular (LV) activation and subsequent contraction, causing remarkable changes in LV mechanics, perfusion and workload and ultimately leading to pathologic cardiac remodelling.
左束支传导阻滞(LBBB)导致左心室(LV)活化模式的改变和随后的收缩，引起LV力学、灌注和负荷的显著变化，最终导致病理心脏重构。
