We present the case of a patient with chest pain, palpitations, atrial fibrillation, left bundle branch block (LBBB) and occasional early narrow QRS complexes. An intracardiac study revealed rate-dependent LBBB with additional hidden rate-dependent slowing in the contralateral bundle branch, resulting in normalization of the early conducted QRS complexes.
我们报告一例有胸痛、心悸、心房颤动、左束支传导阻滞（LBBB）及偶尔出现的早期窄QRS波群的患者。心内研究显示为频率依赖性LBBB，对侧束支存在额外的隐匿性频率依赖性减慢，导致早期下传的QRS波群正常化。
