Several Boston Scientific pacemaker models have a known issue with intermittent oversensing of the minute ventilation sensor when paired with non-Boston Scientific leads. Several of our patients with these hybrid systems have had transient out of range impedances and oversensing after safety switching which we suspected may be related. A retrospective analysis of 395 patients who had pacemakers implanted between 2015-2017 found that transient out of range impedances with safety switching was present in 9% of Boston Scientific pacemakers paired with Abbott or Medtronic leads compared with 0% in other device-lead combinations (P = 0.0089). We postulate that the root cause of the minute ventilation oversensing and transient high impedance issue is the same, a header-lead interaction from low-level incompatibility. Recognizing this issue is critical to prevent unnecessary lead revisions or extractions as it can be prevented with a simple reprogramming of lead pace/sense configuration.
几款波士顿科学公司的起搏器型号在与非波士顿科学公司的导线配对时，存在分钟通气传感器间歇性过度感知的已知问题。我们的几名使用这些混合系统的患者在安全切换后出现了短暂的超出范围的阻抗和过度感知，我们怀疑这可能有关联。一项对2015年至2017年间植入起搏器的395名患者的回顾性分析发现，与其他设备-导线组合中0%的比例相比，9%与雅培或美敦力导线配对的波士顿科学起搏器在安全切换时出现了短暂的超出范围的阻抗（P = 0.0089）。我们推测，分钟通气过度感知和短暂高阻抗问题的根本原因是相同的，即低水平不兼容性导致的接头-导线相互作用。认识到这个问题对于防止不必要的导线修订或拔除至关重要，因为通过简单地重新编程导线的起搏/感知配置就可以预防。
