We present a case of symptomatic intermittent AV block showing during monitorization alternating bundle branch block. Presuming a high need of pacing, conduction system pacing was considered a more physiological alternative in this patient. Left bundle branch pacing restored a stable atrioventricular synchrony with a paced QRS complex similar to the native one and might be a good alternative in these cases.
我们报告了一例在监测过程中出现间歇性房室传导阻滞的症状性病例，期间交替出现束支传导阻滞。鉴于患者对起搏的高度需求，考虑到心脏传导系统起搏是一种更符合生理的替代方法。左束支起搏恢复了稳定的房室同步，起搏后的 QRS 波群与自身相似，在这些情况下可能是一种很好的替代方法。
