Abstract
Progressive aberrancy (defined as beats with QRS duration and morphology between that of sinus rhythm and full aberrancy) occurred in 10 of 32 episodes of atrial pacing in 5 of 11 patients. The episodes resembled fusion beats but were due to bilateral bundle branch delay.
摘要
11例患者中有5例，在32次心房起搏发作中，有10次出现了进行性差异性传导（定义为QRS波时限和形态介于窦性心律和完全性差异性传导之间的搏动）。这些发作类似于融合波，但系双侧束支传导延迟所致。
