摘要

B感噪声是皮下植入式心律转复除颤器（S-ICD）不适当休克（IAS）的罕见原因，它是利用B感对载体的过感和非心脏信号过感的一个因素。b -噪声中的高振幅信号以前未见报道。方法：我们报告了一位47岁男性患者，由于b感噪声，然后是主要和替代载体的强烈噪声，他经历了S-ICD的IAS。结果：对提取的铅进行分析，发现B电极连接处有轻微撕裂，但非生理信号不可重现，设备未发现功能缺陷。结论：b -噪声引起的不适当电击后的高振幅信号是b -噪声的另一种表现。

A Rare Presentation of Sense-B-Noise With High-Amplitude Signals in a Subcutaneous Implantable Cardioverter Defibrillator: Diagnostic Challenges and Management.

Introduction: Sense-B-noise is a rare cause of inappropriate shock (IAS) of subcutaneous implantable cardioverter defibrillator (S-ICD), which is an oversensing of the vectors using the Sense B and a factor of noncardiac signal oversensing. High-amplitude signals in Sense-B-noise have not been reported previously.

Methods: We present a case of a 47-year-old man, who experienced IAS of S-ICD due to sense-B-noise followed by intense noise of primary and alternate vectors.

Results: Analysis of the extracted lead revealed a slight tear in the connection of the Sense B electrode, but the non-physiological signal was not reproducible and no functional defects were identified in the device.

Conclusions: High-amplitude signals after an inappropriate shock due to sense-B-noise are another presentation of Sense-B-noise.
