Abstract
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.
