在尸检中对希氏束起搏(HBP)电极导线位置的评价很少报道。我们报告了一例98岁男性因房室传导阻滞和心力衰竭接受HBP植入的尸检病例。尽管在可接受的阈值下实现了选择性HBP,但在未纠正右束分支阻滞的情况下,刺激至QRS间期相对较长。肉眼检查显示,HBP电极导线插入心室侧,穿过三尖瓣的前间隔连合。甲状腺素运载蛋白心脏淀粉样变性可能影响远端传导系统,导致选择性HBP期间刺激至QRS间期较长。
Evaluations of His bundle pacing (HBP) lead location at autopsy examination have been rarely reported. We report an autopsy case of a 98‐year‐old man who underwent HBP implantation due to atrioventricular block and heart failure. Although selective HBP was achieved with an acceptable threshold, the stimulus‐to‐QRS interval was relatively longer without correction of the right bundle‐branch block. A macroscopic examination revealed that the HBP lead was inserted on the ventricular side passing through the anteroseptal commissure of the tricuspid valve. Transthyretin cardiac amyloidosis may affect the distal conduction system resulting in a long stimulus‐to‐QRS interval during selective HBP.
