摘　　要：分析1例左束支阻滞伴房室阻滞表现"多变"(房室传导8:1→1:1)的心电图,指出房室(束支)阻滞表现(房室传导比例)不仅取决于不应期病理延长的程度,同时受PP间期、逸搏间期和隐匿传导的影响。One ECG case of the changing（A-V conduction changes from 8：1 to 1：1）LBBB with A-V block was analyzed,which indicated that A-V block（BBB）performance（AV conduction ratio）depended on the degree of refractory period extension of pathology,also it was affected by the PP interval,escape interval and the impact of concealed conduction.

关 键 词：房室阻滞 双束支阻滞 有效不应期 PP间期 逸搏间期 隐匿传导
