BackgroundHis bundle pacing (HBP) engaged electrical activation of both ventricles by stimulating the His‐Purkinje network, which could avoid marked ventricles dyssynchrony. The lead was given three to five clockwise rotations at the site with the His potential to anchor the interventricular septum. In 2018, the Multicenter His Bundle Pacing Collaborative Working Group recommended that the His bundle capture threshold should be lower than 2.5 V/1 ms in non‐pacing‐dependent patients, and pacing‐dependent patients should have a lower adjacent ventricular capture threshold as self‐backup. Therefore, to avoid safety issues such as loss of capture caused by increased threshold, we believe that more stringent criteria should be adopted in patients with atrioventricular block (AVB). In previous studies, the connection cable needed to be disconnected during the screwing. When the procedure was finished, the performer found that the patients with His bundle injury could obtain a lower threshold than those without His bundle injury. Although no studies of new bundle branch block (BBB) or AVB by the acute His bundle injury was reported. However, It is worrying that the damage of His bundle seems random during the procedure. How to balance avoiding severe injury with a lower capture threshold? At present, we report a case of light His injury and lower His capture threshold under continuous intracardiac electrocardiogram monitoring.

他的潜在伤害是通过连续记录技术在他的束起搏中拧紧的终点：病例报告

背景希氏束起搏（HBP）通过刺激希氏-浦肯野网络来参与两个心室的电激活，这可以避免明显的心室不同步。导线在该部位顺时针旋转三到五次，具有固定室间隔的潜力。 2018年，多中心希氏束起搏协作工作组建议，非起搏依赖性患者的希氏束夺获阈值应低于2.5V/1ms，起搏依赖性患者应具有较低的邻近心室夺获阈值。 ‐备份。因此，为避免阈值升高导致夺获丢失等安全问题，我们认为对房室传导阻滞（AVB）患者应采用更严格的标准。在之前的研究中，在拧紧过程中需要断开连接电缆。当手术完成后，执行者发现希氏束损伤的患者可以获得比没有希氏束损伤的患者更低的阈值。尽管没有关于急性希氏束损伤引起的新束支传导阻滞（BBB）或AVB的研究报道。然而，令人担忧的是，在手术过程中，他的包裹的损坏似乎是随机的。如何平衡避免重伤与降低捕获阈值？目前，我们报道了一例轻度希氏损伤并在连续心内心电图监测下降低希氏捕获阈值的病例。
