The phenomenon of concealed conduction in His bundle pacing (HBP) has rarely been reported. We report here a patient who had 2: 1 atrioventricular block and complete left bundle branch block was used because of HBP. The patient developed continuous right bundle branch block after the operation. After excluding mechanical damage, we speculate that the mechanism of right bundle branch block in this case was due to concealed conduction.
希氏束起搏(HBP)中的隐匿性传导现象鲜有报道。我们在此报告一名患有2:1房室传导阻滞且因HBP采用完全性左束支传导阻滞的患者。术后该患者出现持续性右束支传导阻滞。排除机械损伤后,我们推测该病例中右束支传导阻滞的机制是隐匿性传导。
