It was reported that this patient was admitted to the hospital due to multiple shocks.A request for estimated remaining longevity was needed to determine if the replacement date for the device should be expedited.Additional information noted that further review of the device data was requested from engineering to provide clarification remaining longevity.Meanwhile technical services (ts) review confirmed noise with no oversensing and no evidence of inappropriate therapy.However, undersensing was exhibited at times leading to unnecessary pacing.Additional information noted that the patient had a left ventricular assist device, which may be the reason for the reported noise artifacts.Ts noted that the left ventricular assist device may be contributing to the baseline noise seen, and also noted that it was likely that this device would trigger end of life (eol) in the very near future.Additional information noted that the patient was in the hospital due to a left ventricular assist device would infection and an inquiry regarding how long the implantable cardioverter defibrillator (icd) would support therapy and advise on the replacement window was needed.The device remains implanted.No adverse patient effects were reported.
