We report two cases of atrial extrasystolic bigeminy manifesting with alternating right and left bundle branch block aberration. The manifestation is explained on the basis of cycle-dependent variations of the bundle branch refractory period with alternate resetting of bundle branch refractoriness.
我们报告了两例房性早搏二联律,表现为右束支传导阻滞与左束支传导阻滞交替出现的差异传导。这种表现是基于束支不应期的周期依赖性变化以及束支不应期的交替重置来解释的。
