Marked QRS widening in patients with left bundle branch block (LBBB) may reduce efficacy of cardiac resynchronization therapy (CRT). We hypothesized that extreme QRS prolongation may accompany right ventricular (RV) dilatation/systolic dysfunction (RVD/RVsD) as well as left ventricular dilatation/systolic dysfunction (LVD/LVsD).

左束支传导阻滞合并心肌病患者右心室扩张和收缩功能障碍及与 QRS 时限的关系

左束支传导阻滞 (LBBB) 患者的 QRS 显着增宽可能会降低心脏再同步化治疗 (CRT) 的疗效。我们假设极端 QRS 延长可能伴随右心室 (RV) 扩张/收缩功能障碍 (RVD/RVsD) 以及左心室扩张/收缩功能障碍 (LVD/LVsD)。
